실험 절차
To crude 2-[bis(methyloxy)methyl]-4-chloro-5,8-dihydropyrido[2,3-d]pyrimidin-7(6H)-one (presumed 6.78 mmol) dissolved in MeOH was added 10% Pd/C (0.15 g). The solution was stirred under an atmosphere of H2 (balloon) overnight. The Pd/C was filtered off and the solution concentrated under vacuum. The crude residue was purified by column chromatography (silica gel) using a DCM/DCM-MeOH—NH4OH (90:10:1) gradient to yield the desired product as a white solid (0.873 g, 58% over 2 steps).
