실험 절차

The procedure of Example 43 is repeated, starting with 5 g. (0.05 mole) of 3-methylpiperidine and 2.5 g. (0.01 mole) of 3-chloro-5-chlorosulfonylbenzoic acid in 15 ml. of methylene chloride, providing 2.7 g., m.p. 177°-179° C. of the crude product. Purification is effected by recrystallization from acetone-hexane, 1.2 g.,m.p. 181°-183° C.
