Versuchsvorschrift

To a suspension of (R)-5-(2-(5-fluoro-2-hydroxyphenyl)-4-hydroxypyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation D; 0.0339 g, 0.0946 mmol) and HATU (0.0540 g, 0.142 mmol) in DMF (0.5 mL) at 0° C. was added (S)-1-amino-3-chloropropan-2-ol hydrochloride (Example 19, Step A; 0.0155 g, 0.142 mmol; prepared according to the method described in Org. Process Res. Dev. 2003, vol. 7, p. 533) and N,N-diisopropylethylamine (0.0494 mL, 0.284 mmol). The resulting mixture was warmed to ambient temperature and stirred for 18 hours. The reaction mixture was diluted with EtOAc (10 mL), washed with brine, dried over MgSO4, filtered, and concentrated under reduced pressure to give the crude material which was purified by silica column chromatography, eluting with 0-20% MeOH/DCM to afford N-((S)-3-chloro-2-hydroxypropyl)-5-((R)-2-(5-fluoro-2-hydroxyphenyl)-4-hydroxypyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (as a mixture of cis and trans isomers, 0.0407 g, 82.2% yield, 86% purity). LC/MS (ES+APCI) m/z=448.1 (M−H).
