Reaction Steps
To a solution of 2-(1,3-dioxolan-2-yl)-1,3-thiazole-5-carbaldehyde (2.25 g) in tetrahydrofuran (20 mL) was slowly added a 1.13M methyllithium diethyl ether solution (12.0 mL) at 0° C. under a nitrogen atmosphere. The reaction mixture was stirred at 0° C. for 30 min, 10% aqueous citric acid solution was added, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The obtained residue was subjected to silica gel column chromatography, and the title compound (1.96 g, yield 80%) was obtained as a colorless oil from a fraction eluted with ethyl acetate-hexane (1:2, volume ratio). MS: 202 (MH+).
