Reaction Steps

To a solution of (S)-4-methanesulfonyl-3-methyl-piperazine-1-carboxylic acid tert-butyl ester (924 mg) in dichloromethane (20 mL) at 0° C. was added dropwise HCl (6.65 mL of a 2 M solution in diethyl ether). The reaction mixture was stirred at room temperature for 2 h. The precipitate formed was then collected by filtration and dried to afford (S)-1-methanesulfonyl-2-methyl-piperazine hydrochloride salt as a white solid (583 mg, 82%).
