Reaction Steps

Under a nitrogen atmosphere, to a solution of (7-methyl-1,4-dioxaspiro[4.5]deca-7-yl)methanol (4.0 g, 21 mmol) in N,N-dimethylformamide (40 ml) was added sodium hydride (1.1 g, 27 mmol) under ice-cooling, and the mixture was stirred for 30 min. Then, to the reaction mixture was added benzyl bromide (3.1 ml, 25 mmol) at room temperature, and the mixture was further stirred for 1 hr. To the reaction mixture were added diethyl ether and water, and the organic layer was separated. Then, the organic layer was washed successively with water and saturated brine, and dried over sodium sulfate. Sodium sulfate was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography to give the title compound (5.7 g, yield 93%).
