実験手順
Treat a cooled solution (0° C.) of 6-(5-amino-4-fluoro-2-methylphenyl)-N,7-dimethylpyrido[2,3-d]pyrimidin-2-amine (0.85 g, 2.86 mmol) in pyridine (10 mL) dropwise with isopropenyl chloroformate (0.281 ml, 2.57 mmol) and stir the mixture for 20 min. at 0° C. Concentrate the mixture to dryness, dissolve the residue in DCM, wash with brine, dry over Na2SO4 and concentrate to dryness to afford the title compound. Use it without purification (assuming 100% yield). MS (m/z): 382.1 (M+1).
