Procedure

The Weinreb amide of 2-methanesulfonyl-6-ethoxy-isonicotinic acid was also converted to (S)-1-(2-methanesulfonyl-6-methoxy-pyridin-4-yl)-ethylamine hydrochloride according to methods described in Example 43 except during the Grignard addition methyl magnesium bromide was added to the Weinreb amide instead of ethyl magnesium chloride to afford the corresponding methyl ketone.
