Procedure

To a solution of cyclopropanecarboxylic acid (1.2 eq.) in anhydrous DMF (2 mL) was distributed EDCI (1.6 eq.), HOBt (1.3 eq.) and TEA (5 eq.). The vial was sealed and stirred for 40 minutes at room temperature. Compound 39 (1 eq. in 1 mL of anhydrous DMF) was added to the vial which was then sealed and stirred overnight at room temperature. The solvent was removed by centrifugal evaporation under reduced pressure. The residue was dissolved in DCM (2 mL), and washed sequentially with 10% K2CO3 solution (1 mL) and water (1 mL). The water wash was then re-extracted with DCM (0.5 mL), the combined organic extracts were evaporated to dryness under reduced pressure. The desired product, Compound 119, was isolated by mass directed LC. LCMS (+ESI) m/z 447.38 [M+H]+
