実験手順

Compound XIV was prepared as in Example 12 at 180° C from p-chlorobenzotrichloride and 2-amino-4-chlorophenol hydrochloride, and purified through a preheated aluminum trioxide column: 16 g of raw product, M.P. 178°-183° C (61% of the theory). Upon recrystallization from benzene: M.P. 190°-192° C.

後処理
