Reaction Steps

To a solution of 57 (135 mg, 0.5 mmol) in n-BuOH (3 mL) in a microwave vial was added 126 (184 mg, 0.75 mmol), then DIPEA (0.26 mL, 1.5 mmol) was added dropwise. The vial was sealed with a rubber septa and heated in the microwave for 90 min at 160° C. The solvent was evaporated under reduced pressure and the crude residue was taken up in DCM (5 mL) and MeOH (5 mL) and the solvent was again concentrated in vacuo. The residue was diluted in DMF (2 mL) and filtered to remove any undissolved solids. The filtrate was concentrated in vacuo. The residue was purified by reverse phase HPLC to afford 13 mg (6%) of I-46.
