Reaction Steps

A solution of 4-Chloro-2-(2-hydroxy-1-hydroxymethyl-ethylamino)-8-(4-trifluoromethyl-phenyl)-8H-pyrido[2,3-d]pyrimidin-7-one (50 mg, 0.12 mmol) in dioxane/H2O (3:1, 4.8 mL) was mixed with 2-methylthiophenyl boronic acid (30.4 mg, 0.18 mmol) and K2CO3 (50.1 mg, 0.36 mmol). The resultant mixture was bubbled with argon for 5 minutes, and added by Pd(PPh3)4 (2.8 mg, 0.0024 mmol). The reaction tube was sealed and heated with “Smith Creator” (microwave, 150° C.) for 15 minutes. The mixture was concentrated under vaco. Flash chromatography (EtOAc/Hexane, 3:1) then provided the title compound (88%): MS (ES) m/z 503 (M+H)+; 1H-NMR(CDCl3) δ 2.48 (s, 3H), 2.65 (s, br, 2H), 3.70 (m, br, 5H), 6.20 (m, br, 1H), 6.45 (m, 1H), 7.43 (m, 6H), 7.68 (m, 1H), 7.83 (m, 2H).
