Reaction Steps

A solution of [(2R)-3-(2-{2-chloro-6-[7-(dimethylamino)-5-azaspiro[2.4]hept-5-yl]-5-fluoro-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl](tetrahydro-2H-pyran-2-yloxy)formamide (0.0961 g, 0.165 mmol) in 4:1 HOAc-water (5 mL) was stirred for 3 days. The solution was concentrated in vacuo and diluted with DCM (100 mL). The solution was washed with sat. aq. NaHCO3 (25 mL), and the organic phase was dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The residue was purified by Gilson RPLC, and the desired fractions were concentrated in vacuo and azeotroped first with MeOH and then with EtOAc. The residue was crystallized from EtOAc-hexanes to provide [(2R)-3-(2-{2-chloro-6-[7-(dimethylamino)-5-azaspiro[2.4]hept-5-yl]-5-fluoro-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl]hydroxyformamide (0.0469 g, 57%, mixture of diastereomers) as a white solid. LCMS: (M+H)+: 498.1.
