Procedure

1-Ethyl-3-(4-(4-morpholino-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl)phenyl)urea (0.0499 g, 0.130 mmol) and 2,6-Dichloropyrazine (0.0311 g, 0.209 mmol) were combined then added dry N,N-Dimethylformamide (0.911 mL, 11.8 mmol) followed by N,N-Diisopropylethylamine (0.0456 mL, 0.262 mmol). The reaction was microwaved on 200 watts, 120° C. for 30 minutes on a CEM microwave. The reaction mixture was purified by HPLC. 1H NMR (400 MHz, DMSO) δ 8.65 (s, 1H), 8.40 (s, 1H), 8.22 (d, J=8.8, 2H), 7.90 (s, 1H), 7.49 (d, J=8.8, 2H), 6.17 (t, J=5.5, 1H), 4.69 (d, J=16.4, 2H), 3.86 (t, J=5.1, 2H), 3.79-3.69 (m, 4 H), 3.49 (d, J=4.3, 4H), 3.18-3.06 (m, 2H), 2.80 (s, 2H), 1.06 (t, J=7.2, 3H).
