Reaction Steps

To a stirred solution of 11-3 (0.2 g, 0.36 mMol), HOBT (0.05 g, 0.4 mMol), and 1H-1,2,3-triazole-4-carboxylic acid (0.05 g, 0.4 mMol) in anhydrous DMF (2 mL) was added DIEA (0.18 mL, 1.1 mMol) followed by EDC (0.08 g, 0.4 mMol). The solution was heated in the microwave reactor for 30 minutes at 80° C. Solution was then treated with 0.5 mL of acetic acid and was heated to 80° C. in the microwave reactor for 10 min. Upon cooling to room temperature, the solution was passed through a syringe filter and purified on a C18 reverse phase HPLC to give 11-4 as a solid. Mass (M+1) calculated: 632.2742 observed: 632.274
