実験手順
4-(N-t-Butoxycarbonyl-4-piperidinyloxy)-2-chlorobenzoic acid methyl ester was saponified to the carboxylic acid with aqueous NaOH in MeOH using the procedure of Step 3 in Example 11. 4-(N-t-Butoxycarbonyl-4-piperidinyloxy)-2-chlorobenzoic acid was obtained as a foam by evaporation of a DCM solution under reduced pressure (90% yield).
