The reaction mixture was heated at reflux for 2 h, cooled to rt, diluted with water and extracted with CH2Cl2 (2×). The combined organics were dried (Na2SO4) and concentrated to give 185 mg (66%) of the title compound as a clear oil which was used without further purification. MS (ESI) mass calcd. For C16H21F3N4O2, 358.40; m/z found 359.1 [M+H]+
