YieldReaction ConditionsOperation in experiment
In methanol; A. Condensed ethylene oxide (7 ml, 125 mmol) was added to a mixture of dibenzylamine (19.2 ml, 100 mmol) in methanol (20 ml) cooled to 0C. After 2 hours at room temperature, the mixture was evaporated without heating above room temperature. The residue was distilled to afford the title compound, bp. 220-225C/25 mm, which solidified on standing, mp 48C.
at 130℃; under 3102.97 Torr; for 18h;Inert atmosphere; Autoclave; Large scale; Dibenzylamine (7627 g) was charged to a 24-L N2-purged pressure vessel. The reactor was pressurized and vented several times with N2, then pressurized with N2 and heated to 130 C. Ethylene oxide (1880 g) was fed into the reactor at such a rate to keep the pressure below 60 psia (?4 h). Upon completing the ethylene oxide addition, the reaction mixture was stirred at 130 C for 14 h. After lowering the temperature to 60 C and releasing pressure, 45%potassium hydroxide (70 g) was added to the vessel and the reaction mixture stirred at 110 C to remove water. The temperature was increased to 130 C and butylene oxide (11,277 g) was fed into the reactor at such a rate to keep the pressure below 60 psia (~31 h). Upon completing the addition, the reaction mixture was stirred for 4 h at 130 C. The reaction mixture was cooled to room temperature and the reaction mixture neutralized with acetic acid.

YieldReaction ConditionsOperation in experiment
83% With potassium carbonate; In ethanol; for 16h;Heating / reflux; Example 1; Dibenzylaminoethanol:; To a 250 mL round bottom flask equipped with stirbar, reflux condensor, nitrogen inlet, and septum was added potassium carbonate (56.5 g, 0.41 mol), ethanol (80 mL), and ethanolamine (9.9 mL, 0.16 mol). The stirred solution was heated to reflux and benzyl chloride (37.9 mL, 0.33 mol) was added via syringe. The resulting solution was stirred for 16 hours at reflux, allowed to cool, then poured into water (200 mL). The solution was extracted with chloroform (3x300 mL). The combined organic layers were dried with magnesium sulfate, filtered, then evaporated to dryness. Recrystallization from hexanes yielded the product as colorless crystals (32.8 g, 83 %). 1H NMR (300 MHz, CDCl3) delta 7.33 (10 H), 3.60 (4 H), 3.58 (2 H), 2.67 (2H). 13C NMR (75 MHz, CDCl3) delta 138.9, 129.2, 128.6, 127.4, 58.7, 58.4, 55.0.

The apparatus was heated up to reflux for 36 hr, after which the insoluble solid was filtered through a medium frit. The filtrate was recovered and ethanol was removed by rotoary evaporation. The viscous liquid was redissolved in ether, the solid suspension removed by filtration and extracted twice against water. The ether solution was kept and the aqueous layer was extracted twice with dichloromethane (2 x 400 mL). The fraction were recombined, dried over MgSO4, stirred over carbon black for 15 min and filtered through a celite pad. Dichloromethane was removed and the solid was redissolved into a minimal amount of ether (combined volume of 300 mL with the first ether fraction, 300 mL). Hexanes ( 1700 mL) was added and the solution was heated up gently till complete dissolution of the product.
