Reaction Steps

To a solution of tert-butyl N-[[4-[5-[6-(4-aminocyclohexen-1-yl)-3-(tert-butoxycarbonylamino)pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (20 mg, 0.03 mmol) in anhydrous DCM (200 μL) was added Et3N (5 mg, 7 μL, 0.05 mmol) and the reaction mixture was cooled in an ice water bath. A solution of propanoyl chloride (3.843 mg, 3.625 μL, 0.04154 mmol) in DCM (0.1 mL) was added dropwise to the above reaction mixture. The reaction mixture was diluted with DCM and washed once with water. The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude material was purified by silica gel column chromatography using 10% MeOH in EtOAc to yield tert-butyl N-[[4-[5-[3-(tert-butoxycarbonylamino)-6-[4-(propanoylamino)cyclohexen-1-yl]pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (21 mg, 96%).
