YieldReaction ConditionsOperation in experiment
With sodium borohydrid; In methanol; water; EXAMPLE 6 Preparation of 5,6,7,8-tetrahydro-6-(3,4-dimethoxybenzyl)-<strong>[253-72-5]1,6-naphthyridine</strong> (Compound No. 46) A solution of <strong>[253-72-5]1,6-naphthyridine</strong> (5.2 g, 0.04 mol) and 3,4-dimethoxybenzyl chloride (8.95 g, 0.048 mol) was refluxed for 3 hours. The precipitated quatenary salt was separated by filtration, dissolved in technical grade methanol (400 ml) and sodium borohydride (15.1 g, 0.4 mol) was added portionwise under ice cooling. After stirring overnight at room temperature, the reaction mixture was evaporated in vacuo, water added and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and evaporated in vacuo. The residue was purified by alumina column chromatography (eluted successively with n-hexane, benzene and chloroform). The resulting residue was recrystallized from ether-n-hexane to afford the Compound No. 46 (6.5 g, 57.2percent) as colorless prisms, mp. 76°-77° C.

YieldReaction ConditionsOperation in experiment
84% To a solution of diethyl 2-[(tert-butoxycarbonyl)amino]malonate (5.22 g, 18.99 mmol, 1 eq) in DMF (80 mL) was added sodium hydride (60% in oil, 0.911 g, 22.79 mmol, 1.2 eq) portionwise.Then, 3,4-dimethoxybenzyl chloride (5.30 g, 28.40 mmol, 1.5 eq) was added dropwise and the solution was stirred for 24 h at room temperature. Water (200 mL) was added and the mixture was extracted with diethyl ether (3*50 mL). The combined organic layers were dried over MgSO4 and the volatiles were removed under reduced pressure. The purification of the crude product by flash chromatography on silica gel with cyclohexane/ethyl acetate (9/1) afforded the diester as pale yellow oil in 84 % yield (6.77 g). 1H NMR (400 MHz, CDCl3) δ 1.25 (t, 3JHH= 7.1 Hz, 6H, H2’), 1.44 (s, 9H, H14), 3.52 (s, 2H, H4), 3.80 (s, 3H, H15), 3.81 (s, 3H, H16), 4.14-4.32 (m, 4H, H1’), 5.73 (br s, 1H, H11), 6.55 (s, 1H, H6), 6.56 (d, 3JHH= 7.9 Hz, 1H, H10), 6.73 (d, 3JHH = 7.9 Hz, 1H, H9). 13C NMR (100 MHz, CDCl3) δ 14.0 (C2’), 28.3 (C14), 37.9 (C4), 55.7 (C15+C16), 62.4 (C1’), 67.2 (C2), 80.1 (C13), 110.9 (C9), 113.4 (C6), 121.9 (C10), 127.7 (C5), 148.1 (C8), 148.5 (C7), 158.8 (C12), 167.6 (C1+C3).
