Reaction Steps

To 5-[5-(azidomethyl)-2-methylphenyl]-1-[(2,2-difluorocyclopropyl)methyl]-3-methyl-1,3-dihydro[1,2,5]thiadiazolo[3,4-b]pyridine 2,2-dioxide (44-1) (480 mg, 1.1 mmol, 1.0 eq) in THF (6.7 mL) was added triphenylphosphine (600 mg, 2.3 mmol, 2.0 eq) followed by water (0.31 mL, 17.1 mmol, 15 eq). The reaction mixture stirred at ambient temperature overnight and was then diluted with EtOAc (100 mL), washed with sodium bicarbonate (4×10 mL) and brine (20 mL), dried over MgSO4, filtered and concentrated. The crude residue was purified by flash chromatography (24 g SiO2, 20-100% EtOAc in hexanes) to afford 1-(3-{1-[(2,2-difluorocyclopropyl)methyl]-3-methyl-2,2-dioxido-1,3-dihydro[1,2,5]thiadiazolo[3,4-b]pyridin-5-yl}-4-methylphenyl)methanamine (44-2). HRMS m/z (M+H) 395.1348 found, 395.1348 required.
