실험 절차

To a solution of 2-amino-5-ethoxy-4-trifluoromethyl-benzonitrile from step 4 (31.62 g, 137.4 mmol) in dry THF (410 mL) was added isoamyl nitrite (40.4 mL, 302 mmol), and the mixture was refluxed for 16 h. The solvent was removed in vacuum to give an orange oil, which was dissolved in sat. NaHCO3-sol., extracted three times with diethyl ether. The combined organic layers were washed with 1 N HCl and brine, dried over Na2SO4. Removal of the solvent in vacuum left an orange oil, which was purified by double Kugefrohr distillation (up to 160° C. bath temperature at 1.5 mbar) to give the title compound as a light yellow solid (25.06 g, 85%). MS (EI) 185.1 [M].
