Reaction Steps
The title compound was prepared by using a similar procedure as described for the preparation of 33 except that 6-chloropicolinaldehyde 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 8:2 hexanes/ethyl acetate, to give 41 (105 mg, 95%) as a clear oil: MS (ES+) m/z340.1 (M+H)+.
