실험 절차

A mixture comprising of 3,5-dichlorobenzyl 3-aminopyrrolidine-1-carboxylate (1 equiv), 4-(1H-1,2,3-triazol-4-yl)butanoic acid (1 equiv.), HATU (1.5 equiv.) and triethylamine (5 equiv.) in dimethylformamide was stirred at RT for 18 hours. Another 1 equivalent of 4-(1H-1,2,3-triazol-4-yl)butanoic acid was added to the reaction mixture and stirring continued for a further 2 hours. The reaction mixture was concentrated under reduced pressure, diluted with water and extracted with DCM. The organic portion was separated, dried over MgSO4, filtered and concentrated under reduced pressure. The crude product was dry loaded using silica onto a 12 g ISCO column, eluting with 0-15% MeOH in DCM. The product fractions were combined and concentrated under reduced pressure. Further purification was carried our using preparative LC-MS. The product fractions were concentrated under reduced pressure to give an aqueous solution and extracted with EtOAc to afford the title compound;
