Reaction Steps
N-[4-(Acetylamino)phenylsulfonyl]piperidine (Example 5) was heated at 100° C. in 20% hydrochloric acid (5 mL) for one hour (TLC ethyl acetate/dichloromethane 8:2). The solution is neutralized at 0° C. with NaOH. The precipitate that forms is filtered and recrystallized from methanol/diethyl ether to afford the desired N-[4-(amino)phenylsulfonyl]piperidine. 70.62% yield; white solid.
