Reaction Steps

The reaction mixture of N-tert-butyl-4-cyano-3-methylbenzenesulfonamide (0.7176 g) and Pd/C (0.97 g) in 1N HCl/EtOH (1.5 ml 1N HCl in 15 ml EtOH) was stirred under H2 for 2 hours. Then 1N HCl (3 ml) was added to improve the reaction progress and it was stirred overnight. The reaction mixture was filtered through a pad of diatomaceous earth, washed with MeOH and concentrated to about 3 ml. The residue was diluted with H2O and lyophilized to give 0.8275 g 4-(aminomethyl)-N-tert-butyl-3-methylbenzenesulfonamide as white powder.
