실험 절차

Methyl 4-{5-[3-amino-4-(2-methylpiperidin-1-yl)phenyl]-1,2,4-oxadiazol-3-yl}-2-fluorobenzoate, prepared as in example 67, Steps 1 and 2, (100 mg; 0.24 mmol) was suspended in a DCM/Pyridine mixture (4 mL, 1:1). Propionyl chloride (25 μL, 0.29 mmol) was added and the mixture was heated to 40° C. for 18 h. After this time, solvents were removed under vacuum and title compound was obtained as an off-white powder after trituration with MeOH (96 mg; 83%). LC/MS (Method B): 467.4 (M+H)+. HPLC (Method A) Rt. 5.69 min (purity: 93.6%).
