Reaction Steps

Caesium carbonate (0.122 g) was added to a solution of 4-[5-(3,5-dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-N-hydroxy-2-methyl-benzamidine (0.1 g) (Example P1) in N,N-dimethylformamide (8 ml). Propargyl bromide (80% w/v in toluene) (0.028 ml) was added. The reaction mixture was stirred at ambient temperature for 20 hours. The reaction mixture was diluted with water and the mixture extracted twice with ethyl acetate. The combined organic phases were washed with water, dried over sodium sulfate, and concentrated. The residue was purified by preparative HPLC to give Compound No. A2 of Table A (0.054 g) as a yellow oil.
