Participants

Reaction Steps

5-Fluoro-2-(methylthio)-6-[(1,3-thiazol-2-ylmethyl)amino]-4(1H)-pyrimidinone hydrazone (0.1958 g, 0.685 mmol) and (2R)-3-cyclopentyl-2-{[formyl(tetrahydro-2H-pyran-2-yloxy)amino]methyl}propanoic acid (0.355 g, 0.823 mmol) were dissolved in DMF (5 mL). NMM (0.30 mL, 2.7286 mmol) was added, followed by HOAt (0.112 g, 0.824 mmol) and EDC (0.157 g, 0.819 mmol). After stirring overnight, the reaction mixture was purified by RP-HPLC to provide [(2R)-2-(cyclopentylmethyl)-3-(2-{5-fluoro-2-(methylthio)-6-[(1,3-thiazol-2-ylmethyl)amino]-4-pyrimidinyl}hydrazino)-3-oxopropyl](tetrahydro-2H-pyran-2-yloxy)formamide as an orange solid (0.2197 g, 57%). LCMS: (M+H)+=568.2.
