Procedure

Sodium hydride (0.04 g) was added to a solution of 2-[2-chloro-4-(4-chlorophenoxy)phenyl]-1-(1,2,4-triazol-1-yl)propan-2-ol (0.5 g) in THF (15 mL). After 30 min benzylbromide (0.27 g) was added and the mixture was stirred for 18 h at reflux. Brine was added and the mixture was extracted with dichloro methane (3×). The combined organic phases were dried, filtered through a silica plug and evaporated. The crude product was purified by column chromatography to yield 0.43 g of the desired compound.
