反应详情

Sodium borohydride (90 mg, 2.38 mmol) was added to a suspension of (2E)-3-[4-(3-pyrazinyl)phenyl]-2-propenal (400 mg, 1.90 mmol, prepared as described in Reference Example 18) in ethanol (5 mL) maintained in a room temperature water bath. After 20 min, the reaction was quenched with water (10 mL), allowed to stir for 10 min, and then concentrated to remove the ethanol. The solids were removed by filtration, washed with water, and dried in vacuo to provide 360 mg (89%) of the title compound. MS 213 (M+H)+.
