実験手順

A mixture of 2-[2-chloro-4-(4-chlorophenoxy)phenyl]-2-methyloxirane (109 g), 1,2,4-triazole (27 g) and sodium hydroxide (16 g) in NMP (1 L) was heated to 110° C. for 1 h. The reaction mixture was then partitioned between MTBE and aq. NaHCO3 solution and the aq. phase was extracted twice with MTBE. The combined organic phases were washed with water (2×), dried and evaporated. The crude product was crystallized from diisopropyl ether.
