Cyclopentane carbonyl chloride (0.187 g, 1.41 mmol) was added to a solution of (6-Fluoro-pyrido[3,4-d]pyrimidin-4-yl)-[3-methyl-4-(piperidin-4-yloxy)-phenyl]-amine (T) (0.50 g, 1.28 mmol) and NEt3 (0.38 g, 3.84 mmol) in CH2Cl2 (15 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 (0.40 g, 70%). LRMS: 450.3 (MH+); 1H NMR (DMSO-d6, 400 MHz): δ 9.90 (s, 1H), δ 8.86 (s, 1H), δ 8.58 (s, 1H), δ 8.19 (s, 1H), δ 7.54-7.56 (m, 2H), δ 7.04 (d, J=9.56 Hz, 1H) δ 4.58-4.61 (m, 1H), δ 3.70-3.72 (m, 2H), δ 3.33-3.44 (m, 2H), δ 2.93-3.008 (m, 1H), δ 2.17 (s, 3H), δ 1.46-1.94 (m, 12H).
