Reaction Steps
A mixture of 7-chloro-2-(2,6-dichloro-benzyl)-oxazolo[5,4-d]pyrimidine (42 mg, 0.13 mmol), 4-trifluoromethyl-phenylamine (22 mg, 0.13 mmol), and p-TsOH.H2O (51 mg, 0.27 mmol) in toluene (2 mL) was heated to 120° C. in a sealed tube. After 2 h, the solution was cooled purified by preparative reverse-phase HPLC to afford the title compound as a colorless solid (20 mg, 34%). MS (ESI): mass calcd. C19H11Cl2F3N4O, 438.0; m/z found, 439.1 [M+H]+. 1H NMR (CDCl3): 8.57 (s, 1H), 7.90 (d, J=8.6 Hz, 2H), 7.76 (s, 1H), 7.62 (d, J=8.6 Hz, 2H), 7.42 (d, J=8.0 Hz, 2H), 7.31-7.27 (m, 1H), 4.66 (s, 2H).
