Reaction Steps

(R)-N4-(1-Methoxymethyl-propyl)-6-(6-methoxy-2-methyl-pyridin-3-yl)-pyrimidine-4,5-diamine (0.2 g, 0.63 mmol) was diluted in ethanol (7 ml) and ethyl pyruvate was added (0.70 ml, 6.3 mmol). The mixture was stirred for 18 hours at which time the solution was concentrated. After concentrating the solution the product was purified by reverse phase HPLC to yield 4.0 mg of (R)-8-(1-methoxymethyl-propyl)-4-(6-methoxy-2-methyl-pyridin-3-yl)-6-methyl-8H-pteridin-7-one (Example 651a). 1H NMR (300 MHz, CDCl3) δ ppm 8.93 (s, 1 H), 7.62 (d, J=8.42 Hz, 1 H), 6.64 (d, J=8.42 Hz, 1 H), 4.23 (m, 1H), 3.94 (s, 3 H), 3.68 (m, 2 H), 3.25 (s, 3 H), 2.45 (s, 3H), 2.34 (s, 3 H), 1.22 (m, 2H), 0.82 (t, J=7.51 Hz, 3 H). MS (EI) 370.3 [(M+H)+, 100].
