Procedure
To a solution of (S)-5-cyano-N-(3,4-dimethoxybenzyl)-2-(2-hydroxy-1-methylethylamino)benzamide (4 g) in pyridine (20 mL) was added methanesulfonyl chloride (1.36 g), and the mixture was stirred for an hour at 0° C. The resulting mixture was diluted with ethyl acetate and washed successively with water and brine. The organic layer was dried over sodium sulfate and evaporated in vacuo. The residue was triturated with diisopropyl ether to give (S)-5-cyano-N-(3,4-dimethoxybenzyl)-2-[2-(methanesulfonyloxy)-1-methylethylamino]benzamide (5.43 g) as an oil.
