実験手順

The title compound was prepared by using a similar procedure as described for the preparation of 33 except that 1H-imidazole-2-carbaldehyde was used instead of 6-bromopicolinaldehyde, and 2-cyano-N-(1-(4-(2-(dimethylamino)ethoxy)phenyl)butyl)acetamide (30) was used instead of 2-cyano-N-(1-(4-(2-(diethylamino)ethoxy)phenyl)butyl) acetamide (29). This produced the crude product which was purified by flash silica gel column chromatography, eluting with 8:92 methanol/dichloromethane, to give 38 (80 mg, 63%) as a light yellow oil: MS (ES+) m/z 453.2 (M+H)+.
