Participants

Reaction Steps

(2S,4S)-tert-butyl 4-(3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)phenyl)-2-(hydroxymethyl)pyrrolidine-1-carboxylate (0.084 g, 0.154 mmol) in 2 mL DCM was added trifluoroacetic acid (0.200 mL) After 3 d, the reaction mixture was concentrated, dissolved in DMSO, filtered, and purified by RPHPLC, gradient, 10-100% ACN/TFA in H2O/TFA. Product-containing fractions were concentrated in vacuo to give ((2S,4S)-4-(3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)phenyl)pyrrolidin-2-yl)methanol. MS (ESI) m/z: Calculated: 445.2; Observed: 445.8 (M++1).
