Reaction Steps

To a mixture of [1-methyl-1-(3-{2-[4-(4-oxo-8-phenyl-3,4-dihydro-2H, 6H-pyrimido[1,2-a]pyrimidin-1-yl)-pyrimidin-2-ylamino]-propyl}-phenyl)-ethyl]-carbamic acid tert-butyl ester (0.25 g, 0.42 mmol) and trifluoroacetic acid (1 mL) in dichloromethane (2 mL) was stirred at room temperature for 30 min. The mixture was washed with saturated sodium bicarbonate, brine, dried over magnesium sulfate and was purified by chromatography on silica gel using 0-8% 2 M NH3 MeOH/CH2Cl2. M+1=496. 1NMR (CDCl3) d (3H, 1.23 ppm), s (6H, 1.47 ppm), m (2H, 2.21 ppm), m (1H, 2.82 ppm), m (1H, 2.98 ppm), s (1H, 3.48 ppm), m (4H, 4.12 ppm), m (1H, 4.35 ppm), d (1H, 4.95 ppm), s (1H, 6.60 ppm), d (1H, 7.09 ppm), d (1H, 7.21 ppm), m (2H, 7.36 ppm), m (3H, 7.44 ppm), dd (2H, 7.91 ppm), d (1H, 8.16 ppm).
