Procedure

The acid (130) (70 mg, 0.111 mmol) was dissolved in DCM (2 ml). EDAC (26 mg, 0.133 mmol) was added and the mixture was stirred at room temperature over night. Cyclopropanesulfonic acid amide (15 mg, 0.122 mmol) and DBU (35 μl, 0.233 mmol) was added and the reaction mixture was stirred at room temperature over night. 5% Citric acid was added to the reaction mixture, and the mixture was extracted with brine, dried over Na2SO4 and purified by column chromatography (DCM/MeOH 20:1) to give the title compound (29 mg, 36%). MS (M+H)=733
