Reaction Steps
A solution of 3,4-dichloroaniline (5 g), N-tert-butoxycarbonyl4-piperidone (11.7 g), sodium triacetoxyborohydride (19.7 g) and acetic acid (7 ml) in dichloroethane (150 ml) was stirred for 16 hours. 2M NaOH solution and ether were added, the organic phase separated, dried and concentrated. The residue was triturated under an isohexane:ethyl acetate, 4:1 mixture and the sub-titled product collected as a solid (7.25 g).
