Reaction Steps

The mixture of 1-(2-methanesulfonyl-pyrimidin-4-yl)-8-phenyl-1,2,3,6-tetrahydro -pyrimido[1,2-a]pyrimidin-4-one (0.20 g, 053 mmol) and {1-[4-(2-amino -ethyl)-phenyl]-ethyl}-carbamic acid tert-butyl ester (0.304 g, 0.79 mmol) in 1:1 dioxane: 1-methyl -2-pyrrolidinone (6 mL) was heated to 100° C. for 17 h. The mixture was partitioned between water (10 mL) and ethyl acetate (20 mL). The organic phase was separated, washed with water, saturated sodium bicarbonate, brine, dried over magnesium sulfate and chromatographed on silica gel using 0-4% MeOH/CH2Cl2to afford a white solid. M+1=568.
