Reaction Steps

A mixture of 2,6-dimethyl-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridin-2-yl)phenol (36.7 mg, 99 μmol) and cesium fluoride (1.5 mg, 9.9 μmol) in anhydrous DMF (0.5 mL) was stirred at 25° C. for 1 h. (S)-(−)-glycidol (14 μl, 207 μmol) was then added, and the resulting mixture was heated under argon at 80° C. for 7 d. The reaction mixture was subsequently cooled to 25° C., filtered through Celite, diluted with DMSO (1.5 mL), and purified by rpHPLC (10-100% CH3CN/water+0.1% TFA) to provide (S)-3-(2,6-dimethyl-4-(5-(1-phenylcyclopropyl)-thiazolo[5,4-b]pyridin-2-yl)phenoxy)-propane-1,2-diol as a light yellow solid. MS (ESI) m/z: Calculated: 446.2; Observed: 447.2 (M++1).
