Participants

Reaction Steps

To a solution of (R)-5-(2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation K, 30 mg, 0.084 mmol) in anhydrous CH2Cl2 (2 mL) was added HOBt (34 mg, 0.25 mmol) followed by EDCI (48 mg, 0.25 mmol). The solution was stirred for 30 minutes, then treated with (trans)-4-aminocyclohexanol (29 mg, 0.25 mmol) followed by triethylamine (35 μL, 0.25 mmol). After stirring at ambient temperature for 5 hours, the reaction mixture was diluted with EtOAc, washed with saturated NH4Cl (20 mL), saturated NaHCO3, and brine, then dried (Na2SO4), filtered and concentrated. The crude material was purified by silica chromatography (4% MeOH/CH2Cl2) to yield the final product as white solid (23 mg, 60%). LCMS (apci) m/z=455.1 (M+H).
