To a mixture of 8-(morpholin-4-yl)-2,3-dihydroimidazo[1,2-c]quinazolin-5-amine hydrobromide 105.7 mg (0.30 mmol), 6-(acetamido)nicotinic acid 81.1 mg (0.45 mmol) and N,N-diisopropylethylamine 0.26 mL (1.50 mmol) in N,N-dimethylformamide 2 mL was added PyBOP((1H-1,2,3-benzotriazol-1-yloxy)(tripyrrolidin-1-yl)phosphonium hexafluorophosphate) 234.2 mg (0.45 mmol) and stirred at 90° C. for 16 hours. After cooling to room temperature, saturated NaHCO3 solution was added. The precipitate was collected and washed with water, methanol, and diethyl ether to give the title compound 41.1 mg as yellow solid. Yield 31.6%.
