Procedure

To a mixture of 5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (50 mg, 0.11 mmol), crude 1-(4,6-dimethylpyrimidin-2-yl)cyclopropanamine (100 mg) in 2 ml DMF at room temperature was added BOP (100 mg, 0.22 M, 2.0 eq.) and triethyl amine (0.046 ml 0.33 M, 3.0 eq.), and the mixture stirred overnight under an N2 atmosphere. The mixture was poured into crushed ice, and the solid precipitate was filtered and dried. The product obtained was further purified by preparative HPLC. Yield: 15 mg (24%) 1H NMR (400 MHz, CD3OD): δ 7.97-7.94 (m, 2H), 7.89 (s, 1H), 7.51 (d, J=8.5 Hz, 1H), 7.31-7.25 (m, 3H), 7.19 (s, 1H), 7.14 (s, 1H), 4.11 (s, 3H), 2.96 (s, 3H), 2.48 (s, 6H), 2.31 (s, 3H), 1.86-1.83 (m, 2H), 1.55-1.52 (m, 2H). 19F NMR (376.57 MHz, CD3OD) δ−77.40 (TFA), −112.33, −122.75 (CFCl3 as reference).
