HCID 6228Dimethylformamide溶媒

実験手順

A mixture of the amine from example 4 (500 mg, 1.31 mmol), methyl bromoacetate (260 mg, 1.70 mmol) and potassium carbonate (220 mg, 1.59 mmol) in N,N-dimethylformamide (15 ml) was stirred at room temperature for 72 hours. The mixture was evaporated under reduced pressure and the residue purified directly by column chromatography on silica gel using dichloromethane:methanol (93:7) as eluant to afford the title compound.
