Example 9. (3 -Difluoro-5-(5-methyl-[l ,2,41triazolo[l ,5-alpyrimidin-7-yl)piperidin- l-yl)(3-iodo-4-methoxy hen l)methanone. To a solution of 7-(5,5-difluoropiperidin-3-yl)-5-methyl-[l ,2,4]triazolo[l,5- a]pyrimidine (35 mg, 0.10 mmol) in DCM (0.32 mL) was added TEA (15.94 mu, 0.1 1 mmol), 3-iodo-4-methoxybenzoic acid (26.50 mg, 0.10 mmol), HOBt (17.51 mg, 0.1 1 mmol) and EDCI (21.92 mg, 0.1 1 mmol). The reaction was stirred at rt for 16 h. The crude reaction was filtered and the residue was purified by preparative reverse phase HPLC to afford the title compound (14 mg, 29%). 1H NMR (400 MHz, CDC13) delta = 8.58 (s, 1H), 7.95 (d, J = 1.96 Hz, 1H), 7.50 (dd, J = 8.41 , 2.15 Hz, 1H), 6.94 (br s, 1H), 6.86 (d, J = 8.61 Hz, 1H), 4.52 – 4.85 (m, 1H), 4.03 (br s, 2H), 3.88 – 3.99 (m, 3H), 3.23 – 3.58 (m, 2H), 2.65 – 2.76 (m, 5H), [M+H] = 514.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Iodo-4-methoxybenzoic acid, its application will become more common.
