실험 절차
To a solution of 8.7 g (5-(trifluoromethyl)isoxazol-3-yl)methyl methanesulfonate in 87 mL DMF was added 9.23 g sodium azide. The reaction mixture was stirred 3 h at RT. 80 mL water was added under cooling. The mixture was extracted with diethyl ether (3×100 mL) and the organic layers were washed with water (3×100 mL) and then with sat. NaCl solution (1×100 mL). The combined organic layer was dried over Na2SO4, filtered off and concentrated in vacuo to yield 6.26 g of the title compound as a brown oil.
