Procedure

To a solution of 4-[5-(3,5-Dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-N′-hydroxy-2,N,N-trimethyl-benzamidine (200 mg) in DMF (5 mL) was added a solution of LiOH (31 mg) in water (2 mL), before adding dimethyl sulfate (0.21 mL, 0.27 g). The mixture was stirred at room temperature over night and poured onto water. The aqueous layer was extracted with MTBE and the combined organic layers were washed with water, dried (Na2SO4) and evaporated to yield the title compound (170 mg, 83%).
