Reaction Steps

1-(2-methanesulfonyl-pyrimidin-4-yl)-8-phenyl-1,2,3,6-tetrahydro-pyrimido[1,2-a]pyrimidin-4-one (1.1 g, 2.9 mmol) and [4-(2-amino-propyl)-phenyl]-methanol (0.96 g, 5.8 mmol) in 1:1 dioxane: 1-methyl-2-pyrrolidinone (16 mL) was heated to 100° C. for 20 h. The mixture was partitioned between water (30 mL) and ethyl acetate (60 mL). The organic phase was separated, washed with water, saturated sodium bicarbonate, brine, dried over magnesium sulfate and chromatographed on silica gel using 0-8% 2M NH3 MeOH/CH2Cl2 to afford a white solid. M+1=469. 1NMR (CDCl3) d (3H, 1.21 ppm), s (1H, 1.79 ppm), m (2H, 2.22 ppm), m(1H, 2.79 ppm), m (1H, 2.98 ppm), m (4H, 4.11 ppm), m (1H, 4.13 ppm), b(3H, 4.68 ppm), s (1H, 6.60 ppm), d (2H, 7.21 ppm), d (3H, 7.29 ppm), m (3H, 7.44 ppm), dd (2H, 7.91 ppm), d (1H, 8.17 ppm).
