Reaction Steps

[3-(4-Bromo-3-fluorophenyl)-4,5-dihydroisoxazol-5-yl]methane sulfonate (9.85 g, 28 mmol) was dissolved in dry DMF (100 ml). Sodium azide (2.73 g, 42 mmol) was added and the reaction mixture stirred at 80° C. for 5 hours. The reaction mixture was concentrated in vacuo then azeotroped with xylene (20 ml). The crude product was dissolved in ethyl acetate (100 ml) and washed with water (100 ml). The organic layer was separated, dried over magnesium sulfate, filtered then concentrated in vacuo to yield 8.046 g of the desired compound.
