The reaction mixture is stirred overnight with warming to rt. Saturated sodium bicarbonate solution is added and the reaction mixture is extracted with ethyl acetate, washed with brine, dried over sodium sulfate and concentrated in vacuo. The crude material is first purified by column chromatography (eluent: methanol/methylene chloride) and then purified by HPLC to afford both the dichloro (LCMS: (FA) M+1 588) and mono chloro (LCMS: (FA) M+1 554) title compounds.

This mixture was warmed to ambient temperature and stirred for 4 hours. At this time HPLC analysis showed that <1% starting material or reaction intermediates remained. To the reaction was added ethyl acetate (20 mL) and water (20 mL). After this addition was complete saturated Na2CO3 (80.0 mL) was added until the pH was between 6-7. After stirring for 10 minutes the phases were separated and the aqueous layer was back extracted with ethyl acetate (20 mL). The organic layers were combined and dried with Na2SO4. The organic layer was then concentrated to 4 vol of ethyl acetate. The solution started to precipitate within 5 minutes. This mixture was stirred for 16 hours. The resulting white solids were collected using a filter over 5 minutes. The solid was dried in a vacuum oven under full vacuum overnight (35° C., 16 hours). This yielded (s.e.)-((1R,2R,3S,4R)-2,3-dihydroxy-4-(2-(3-(trifluoromethylthio)-phenyl)pyrazolo[1,5-a]pyrimidin-7-ylamino)cyclopentyl)methyl sulfamate anhydrous Form 1. (2.85 g, 84%).
