실험 절차

N-[3-[(4aR,7aS)-2-Benzamido-6-(5-fluoropyrimidin-2-yl)-4,4a,5,7-tetrahydropyrrolo[3,4-d][1,3]thiazin-7a-yl]phenyl]-5-cyano-pyridine-2-carboxamide (360 mg, 0.59 mmol) is dissolved in ethanol (10 mL) and dichloromethane (2 mL). 0-Methylhydroxylamine hydrochloride (504 mg, 5.91 mmol) and pyridine (478 μL, 5.91 mmol) are added and the reaction is stirred at room temperature over the weekend (70 hrs). The reaction is warmed to 60° C. and stirred for 24 hrs. The reaction is concentrated to give the crude product and purified via silica gel chromatography using a 0-10% gradient of 7 N ammonia methanol in dichloromethane to give the free base of the title compound. This material is dissolved in dichloromethane (5 mL) and 1 M hydrogen chloride in diethyl ether (0.54 mL, 540 μmol) is added. The solvent is removed in vacuo to give the title compound (240 mg, 75%). ES/MS (m/e): 475 (M+H).
