Procedure

2,6-difluorophenyl Isocyanate (0.199 g, 1.28 mmol) was added to a solution of (6-Fluoro-pyrido[3,4-d]pyrimidin-4-yl)-[3-methyl-4-(piperidin-4-yloxy)-phenyl]-amine hydrochloride (T) (500 mg, 1.28 mmol) and NEt3 (0.388 g, 3.84 mmol) in CH2Cl2 (20 mL). After 1 h the reaction was quenched with water, the layers were separated and the organic layer was washed with 1N NaOH and water, dried over Na2SO4, and concentrated. Purification by flash column chromatography (CH2Cl2/MeOH 97:3) afforded the title compound as a yellow solid (0.50 g, 77%). LRMS: 509.2 (MH+); 1H NMR (DMSO-d6, 400 MHz): δ 9.90 (s, 1H), δ 8.86 (s, 1H), δ 8.58 (s, 1H), δ 8.28 (s, 1H), δ 8.19 (s, 1H), δ 7.55-7.58 (m, 2H), δ 7.20-7.27 (m, 1H), δ 7.04-7.10 (m, 3H), δ 4.58-4.61 (m, 1H), δ 3.69-3.73 (m, 2H), δ 3.33-3.98 (m, 2H), δ 2.19 (s, 3H), δ 1.91-1.96 (m, 2H), δ 1.60-1.66 (m, 2H).
