Reaction Steps

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 (S)-2-cyano-N-(1-phenylbutyl)acetamide 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 1:1 hexanes/ethyl acetate, to give 42 (92 mg, 94%) as a clear oil: MS (ES+) m/z 295.1 (M+H)+.
