Reaction Steps

(R)-6-(2-Chloro-4-methoxy-phenyl)-N4-(1-methoxymethyl-propyl)-pyrimidine-4,5-diamine (0.20 g, 0.60 mmol) was diluted in ethanol (6 ml) and ethyl pyruvate was added (0.68 ml, 6.0 mmol). The mixture was stirred for 18 hours at which time the solution was concentrated. The residue was diluted in glacial acetic acid (10 ml) and warmed to 100° C. for 1 hour. After concentrating the solution the product was purified by reverse phase HPLC to yield 5.0 mg of (R)-4-(2-chloro-4-methoxy-phenyl)-8-(1-methoxymethyl-propyl)-6-methyl-8H-pteridin-7-one (Example 571a). 1H NMR (300 MHz, CDCl3) δ ppm 9.02 (s, 1 H), 7.41 (d, J=8.79 Hz, 1 H), 7.05 (d, J=2.56 Hz, 1 H), 6.93 (dd, J=8.79, 2.56 Hz, 1 H), 3.87 (s, 3 H), 3.73 (m, 2 H), 3.29 (s, 3 H), 2.63 (m, 2H), 2.49 (s, 3 H), 2.10 (m, 2 H), 0.87 (t, J=7.51 Hz, 3 H). MS (AP) 389.3 [(M+H)+, 100].
