Reaction Steps
A solution of 0.22 g (0.52 mmol) of (+/−)9-(2-chloro-6,7-dihydro-5H-[1]pyrindin-6-ylmethyl)-7,7-dimethyl-2-(pyrimidin-4-yl)-6,7,8,9-tetrahydro-pyrimido[1,2-a]pyrimidin-4-one in 3 ml of anhydrous toluene and 0.5 ml of ethanol was treated with 0.625 ml (2M solution in water) of sodium carbonate, 36 mg (0.03 mmol) of tetrakis(triphenylphosphine)palladium and 0.095 g (0.780 mmol) of phenyl-boronic acid. After being stirred for 24 h at 140° C., water was added, the mixture was extracted with dichloromethane. The organic phase was dried and evaporated to give crude product, which was purified by silica gel chromatography, eluting with dichloromethane/methanol/ammonia in the proportions 99/1/0.1 to give 0.133 g of pure product obtained in the form of free base. Mp: 209-211° C.
