Abstract

1412 (5.1 mg, 0.02 mmol) and benzaldehyde dimethyl acetal (54.8 mg, 0.36 mmol) in dichloromethane (2.5 ml) were added triethylsilane (65.0 mg, 0.56 mmol) in dichloromethane (1.5 m1) and acetyl bromide (96.8 mg, 0.79 mmol) in dichloro- methane (1 ml), successively at room temperature under argon atmosphere. The mixture was stirred for 3 h at this temperature, and quenched with a phosphate buffer (pH 7). The organic materials were extracted with dichloromethane ...
