Reaction Steps

Methyl 2-(4-(2-((1S,2R)-2-(1-(3-isopropyl-1,2,4-oxadiazol-5-yl)piperidin-4-yl)cyclopropyl)ethoxy)phenyl)acetate (0.55 g, 1.28 mmol) was dissolved in MeOH (5 ml) and lithium hydroxide (154 mg, 6.43 mmol) in 2 mL of water was added. The mixture was stirred at RT for 1 h and neutralized to pH 6 with 5 N HCl, extracted with EtOAc (50 ml). The EtOAc phase was dried over MgSO4, and evaporated to afford 514 mg (97%) of the desired product. LC/MS (m/z): 414 (M+H)+.
