YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In dimethyl sulfoxide; Example 3 Preparation of 1-Hydroxy-6-(3,5,5-trimethylhexyloxy) -pyridine-2 (1H) -one The 0.82 g (0.0050 moles) of 2,6-dichloropyridine N-oxide and 0.80 g (90percent) (0.0050 moles) of <strong>[3452-97-9]3,5,5-trimethyl-1-hexanol</strong> was reacted with 0.206 g (0.0050 moles) of ground sodium hydroxide in 8.2 ml of DMSO at 80° C. for 8.5 hours to give 2-chloro-6-(3,5,5trimethylhexyloxy)pyridine N-oxide. It was reacted with 0.600 g (0.015 moles) of ground sodium hydroxide at 80° C. for 4 hours to give 1-hydroxy-6-(3,5,5-trimethyl-hexyloxy) pyridine-2(1H)-one. After cooling, it was added 74 ml of water and was adjusted with 6N HCL to pH 3. The precipitate was filtered and washed with water to give 0.577 g (45percent). It was recrystallized from ethyl acetate and hexanes: mp 130.5°-131° C.

YieldReaction ConditionsOperation in experiment
48% With pyridine; at 20℃; for 2h; A mixture of 44 (300 mg, 1.56 mmol), 2,6-dichloropyridine N-oxide (256 mg, 1.56 mmol) in pyridine (6 mL) was stirred for 2 h at rt. Then, 2 N HCl (50 mL) was added to the reaction, followed by filtration, and removal of the solvent in vacuo. The residue was purified by column chromatography (eluent: CH2Cl2/EtOAc 99:1) to afford the desired compound (9) as white crystals in 48% yield.
