Procedure

2-{4-[1-(4-trifluoromethoxyphenyl)-1H-[1,2,4]triazol-3-yl]phenyl}cyclopropylamine (46.0 mg, 0.13 mmol, 1.0 equiv) was dissolved in CH2Cl2 (0.55 mL) under N2. 4-Dimethylaminopyridine (DMAP; 0.8 mg, 0.006 mmol, 0.05 equiv) and Et3N (27 μL, 0.19 mmol, 1.5 equiv) were added, followed by mesityl chloroformate prepared above (33 mg, 0.17 mmol, 1.2 equiv). The reaction was stirred for 5 min and was then quenched with NaHCO3 (aq). The layers were separated, and the aqueous layer was extracted twice more with CH2Cl2. The combined organic extracts were concentrated, and the crude product was purified by silica gel chromatography (EtOAc-hexanes gradient) to afford the title compound as a white solid (53.0 mg, 79%): mp 199-202° C.; 1H NMR (400 MHz, CDCl3, data for major rotamer) δ 8.54 (s, 1H), 8.08 (d, J=8.3 Hz, 2H), 7.78 (d, J=9.0 Hz, 2H), 7.39 (d, J=0.7 Hz, 2H), 7.32-7.21 (m, 2H), 6.86 (s, 2H), 5.71-5.36 (m, 0.7H), 5.22-4.82 (m, 0.3H), 3.09-2.81 (m, 1H), 2.26 (s, 4H), 2.17 (s, 6H), 1.43-1.26 (m, 2H); ESIMS m/z 523 (M+H).
