Participants

Reaction Steps

4-(2-Bromoethyl)benzaldehyde (3.245 g) was dissolved in tetrahydrofuran (60 ml). Under ice cooling, a 3 M solution (4.9 ml) of methylmagnesium bromide in diethyl ether was added dropwise thereinto and the resultant mixture was stirred for 1.5 hr. After adding water and ethyl acetate, the layers were separated and the organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was then purified by silica gel column chromatography (hexane/ethyl acetate system) to give the title compound (2.745 g) as a brown oil (yield: 83.8%).
