Participants

Reaction Steps

To a solution of 3-[2-(1H-indazol-4-yl-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl]-propionic acid (145 mg) in DMF (5 mL) at room temperature was added carbonyliimidazole (115 mg). The reaction mixture was then stirred at room temperature for 1 h. Then, triethylamine (0.15 mL) and dimethylamine hydrochloride (58 mg) were added and the solution was stirred at room temperature for 16 h. The reaction was then quenched with water (20 mL) and extracted into ethyl acetate (2×20 mL). The combined organics were washed with aqueous brine solution (3×20 mL), dried (MgSO4), concentrated and purified using column chromatography to give 148 as a white solid (96 mg). NMR: DMSO: 2.68-2.84 (2 H, m, CH2), 2.86 (3 H, s, Me), 3.02 (3 H, s, Me), 3.18 (2 H, t, J 7.22, CH2), 3.79-3.84 (4 H, m, CH2), 3.98-4.02 (4 H, m, CH2), 7.40 (1 H, s, Ar), 7.44 (1 H, t, J 8.0, Ar), 7.62 (1 H, d, J 8.15, Ar), 8.21 (1 H, d, J 7.35, Ar), 8.85 (1 H, s, Ar) and 13.15 (1 H, s, NH). MS: (ESI+): MH+ 437.22
