Participants

Reaction Steps

To a solution of [(2,6-difluoro-4-{2-[(1S,2R)-2-{1-[3-(propan-2-yl)-1,2,4-oxadiazol-5-yl]piperidin-4-yl}cyclopropyl]ethoxy}phenyl)acetic acid (35.0 mg, 0.078 mmol) (from example 2, step B) in 1 ml anhydrous DMF at RT was added azetidin-3-ol hydrochloride salt (8.53 mg, 0.078 mmol) and N,N-diisopropylethylamine (0.041 ml, 0.234 mmol). o-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (59.2 mg, 0.156 mmol) was added into the solution and stirred at RT for 4 hrs. The reaction mixture was filtered and purified by reverse-phase HPLC (SunFire Prep C18 OBD 5 um 19×100 mm column; 35-95% acetonitrile in 0.1% formic acid in water gradient) to give the title compound. LC/MS (m/z): 505.4 (M+H)+. GPR119 Human EC50: 0.96 nM
