Procedure

To a solution of compound 8f (100 mg, 0.3 mmol), compound 8g (44 mg, 0.31 mmol), and DIPEA (80 mg, 0.6 mmol) in dimethylformamide was added HBTU (141 mg, 0.37 mmol). After stirring for 18 h, the reaction was purified by preparative reverse phase HPLC to yield compound 299. 1H NMR (400 MHz, MeOD): δ 7.93-8.03 (m, 1H), 7.61-7.71 (m, 4H), 7.54-7.61 (m, 2H), 7.43-7.50 (m, 2H), 7.35-7.43 (m, 2H), 7.27-7.35 (m, 1H), 7.07-7.20 (m, 2H), 4.55-4.67 (m, 1H), 4.43-4.53 (m, 1H), 4.32-4.43 (m, 1H), 4.19-4.32 (m, 1H), 3.89-4.00 (m, 1H), 3.66-3.89 (m, 4H), 3.08 (br. s., 4H); MS m/z (M+H+) 444.2 (calculated for C27H26FN3O2, 443.53).
