Reaction Steps

Methanesulfonic acid 3-(4-bromo-3-fluoro-phenyl)-4,5-dihydro-isoxazol-5-ylmethyl ester (38.6 g, 111.9 mmol) was added to dimethyl formamide (100 ml) followed by addition of sodium azide (14.5 g, 223.8 mmol). The mixture was heated to 75° C. for five hours and then added to aqueous sodium chloride (200 ml) followed by extraction with ethyl acetate (3×200 ml). The organic layers were combined, dried over sodium sulfate, and concentrated in vacuo to yield the desired product (31 g).
