Reaction Steps
To a solution of 4-[2-(ethylsulfinyl)-6-phenylpyrido[2,3-d]pyrimidin-7-yl]benzaldehyde (6-4; 100 mg, 0.258 mmole) in dioxane (1 mL) was added N,N-dimethylpiperazine-1-carboxamide (48 mg, 0.309 mmole) and heated to 150° C. in a microwave reactor for 30 min. The mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (100% Hex. to 100% EtOAc) to give the title compound. LRMS m/z (M+H) Calcd: 467.2, found 467.1.
