Методика

A stirring solution of 4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)butanoic acid (1.2 equivalents), HATU (1.2 equivalents), and Hunig's base (3 equivalents) in DMF and dichloromethane is allowed to stir for 30 minutes. Compound #115 (1 equivalent) is then added as a solution in dichloromethane and DMF. Reaction is monitored by LC-MS. Reaction is concentrated down and purification is completed by Isco medium pressure reverse phase chromatography (Gradient: 5%-100% water in acetonitrile).
