Procedure

To a solution of 5-chloro-3-methyl-7-(4-morpholinophenyl)pyrido[4,3-d]pyrimidin-4(3H)-one (6.0 mg, 0.017 mmol) in 1,4-dioxane (0.5 mL) were added crude 5-(hydroxymethyl)thiophen-2-ylboronic acid from Step A, 2M aqueous Na2CO3 solution (0.1 mL, 0.2 mmol), and a catalytic amount of Pd(PPh3)4. The reaction mixture was purged with N2 and heated at 140° C. by a microwave reactor for 15 minutes. The mixture was then cooled, quenched with H2O, extracted with EtOAc, and purified by preparatory LC/MS to provide the title compound; ESI-MS m/z 435.1 (MH+).
