Reaction Steps
In an analogous manner to that described in Example 13 (f), by reacting (3RS,4RS,5SR)-3-hydroxy-5-hydroxymethyl-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-piperidine-1-carboxylic acid tert-butyl ester with triphenylchloromethane there was obtained (3RS,4RS,5SR)-3-hydroxy-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-5-trityloxymethyl-piperidine-1-carboxylic acid tert-butyl ester as a colorless foam; MS: 761 (M+NH4)+.
