Reaction Steps

4-(2-Hydroxyphenyl piperidine. 1-Benzyloxycarbonyl-4-(2-benzyloxyphenyl)piperidine was subjected to a procedure similar to that described in Example 10 sub-part c. to give 4-(2-hydroxyphenyl)piperidine as a brown solid (0.36 g); NMR (CDCl3): 1.7-1.9 (m,4), 2.77-2.86 (m,2), 2.99-3.04 (m,1), 3.23 (d,2, J=12), 4.17 (s,2), 6.72 (d,1, J=8), 6.84 (t,1, J=7), 7.05 (m,1); MS: m/z=178(M+1). This material was used in the next step without further purification.
