実験手順

To a solution of 2-bromo-thiazole-5-carbaldehyde (1.00 g, 5.21 mmol) in THF (10 mL) was added a 3 M solution of ethylmagnesium bromide (5.00 mL, 15.0 mmol) in diethyl ether. The mixture was stirred for 18 hours. The reaction was poured into saturated aqueous ammonium chloride (100 mL) containing crushed ice and diluted with EtOAc (100 mL). The organic phase was separated, washed with saturated aqueous sodium bicarbonate solution (100 mL), dried over sodium sulfate, filtered and concentrated. The compound was purified by silica gel chromatography eluting with a gradient of 0-100% ethyl acetate in hexanes provided 1-(2-bromo-thiazol-5-yl)-propan-1-ol.
