A solution of 0.050 g (0.00018 mole) of (rac)-2-chloro-9-cyclobutyl-5,7-dimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-52), 0.047 g (0.00018 mole) of 4-amino-3-methoxy-N-(1-methyl-piperidin-4-yl)-benzamide, 0.053 g (0.00028 mole) of p-toluenesulfonic acid monohydrate and 4.0 mL of 2-propanol was heated at 180 degrees for 2 hours in a microwave reactor. The reaction mixture was concentrated and the residue diluted with dichloromethane and washed twice with saturated sodium bicarbonate solution. The aqueous phase was extracted with dichloromethane. The combined organic phases were washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with dichloromethane-methanol (100:0-75:25 n) to give 0.0535 g of (rac)-4-(9-cyclobutyl-5,7-dimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(1-methyl-piperidin-4-yl)-benzamide (I-52) as white powder. HRMS (ES+) m/z Calcd for C27H37N7O3+H [(M+H)+]: 508.3031. Found: 508.3031.
