실험 절차

3-cyclopropyl-3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)propanenitrile (Example 2; 84.6 mg, 0.236 mmol) and 1-iodopyrrolidine-2,5-dione (79.7 mg, 0.354 mmol) were suspended in DCM (2.36 mL, 0.236 mmol) and stirred at ambient temperature for 15 hours. The reaction mixture was diluted in EtOAc and washed with saturated sodium bicarbonate and brine. The organic layer was dried with MgSO4, filtered and concentrated in vacuo. Purification of the resulting crude material by silica chromatography using 0-5% MeOH/EtOAc gradient afforded 3-cyclopropyl-3-(4-(3-iodo-7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)propanenitrile (86.5 mg, 75.7% yield). MS (apci) m/z=485.2 (M+H).
