Anhydrous DMF was sparged with argon gas for 1 h before being used. Tert-butyl 7-iodo-3,4,4a,9a-tetrahydro[1]benzofuro[2,3-c]pyridine-2(1H)-carboxylate (1 g, 2.5 mmol) sodium tert-butoxide (723 mg, 7.5 mmol), neocuproine (52 mg, 0.25 mmol) and copper (I) iodide (290 mg, 1.5 mmol) were dissolved in anhydrous DMF (20 mL). To this mixture was added a 2M solution of methylamine in THF (6 mL) and the reaction shaken at 80° C. for 16 h. The solvent was evaporated and the residue dissolved in DCM and washed with H2O (3×). The solvent was evaporated and the crude residue used as such in the next reaction step.
