Reaction Steps

4-[(3-Bromo-thiophen-2-yl)-(methyl-hydrazono)-methyl]-piperidine-1-carboxylic acid tert-butyl ester (700 mg, 1.74 mmol) was mixed with CuI (20 mg), CsCO3 (650 mg, 1.15 eq) in methoxyethanol (10 mL). The mixture was heated to 70° C. for 2 hr. then stirred overnight at room temperature. The solvent was stripped on rotary evaporator. The residue was extracted into EtOAc then washed with brine and concentrated down to an oil. This oil was purified via chromatography (eluted with 0-10% MeOH in DCM) yielding 520 mg (68%) of the desired product.
