Participants

Reaction Steps

To a tetrahydrofuran (5 mL) solution of 6-(2,4-difluorophenoxy)-8-((S)-2-hydroxypropyl)-2-methanesulfonyl-8H-pyrido[2,3-d]pyrimidin-7-one (400 mg, 1 mmol) was added (R)-2-amino-1-propanol (0.38 mL, 5 mmol) and stirred overnight at room temperature. Concentrated under vacuum and chromatographed on silica gel eluding with 2% methanol in dichloromethane and converted to the hydrochloride salt to give 370 mg 6-(2,4-difluoro-phenoxy)-2-((R)-2-hydroxy-1-methyl-ethylamino)-8-((S)-2-hydroxy-propyl)-8H-pyrido[2,3-d]pyrimidin-7-one (mass spec. M+1=407, MP=174.9-178.1° C.).
