Procedure

To a solution of Intermediate 58 (433 mg, 1.38 mmol) in DCM (5 mL) was added 2-chloro-3-(trifluoromethyl)benzoic acid (310.3 mg, 1.38 mmol), triethylamine (1.15 mL, 8.29 mmol) and BOP (611.03 mg, 1.38 mmol). The solution was allowed to stir overnight. Following dilution with water, the mixture was extracted with DCM three times. The combined organic layers were dried over Na2SO4 and conc. The resulting residue was purified by basic HPLC (0-99% acetonitrile). (356 mg, 56%). MS (ESI): mass calcd. for C20H15ClF3N3O, 405.81. m/z found, 406.2 [M+H]+. 1H NMR (CDCl3): 7.76 (ddd, J=12.1, 7.8, 1.4 Hz, 1H), 7.56-7.33 (m, 7H), 5.17-4.97 (m, 1H), 4.52-4.33 (m, 1H), 4.28 (dt, J=12.9, 5.4 Hz, 1H), 3.99-3.83 (m, 1H), 3.54-3.41 (m, 1H), 2.97 (t, J=5.8 Hz, 1H), 2.79-2.68 (m, 1H).
