Reaction Conditions

Reaction Steps

A mixture of dibromoisoquinoline (150 mg, 0.52 mmol), tert-Butyl 1,4-diazepane-1-carboxylate (104 mg, 0.52 mmol) and potassium carbonate (144 mg, 1.04 mmol) in DMF (5 ml) was heated to 90° C. for 18 hours. The reaction mixture was allowed to cool down to room temperature and was partitioned between ethyl acetate and a saturated solution of sodium bicarbonate. The organic layer was separated, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography to afford the title compound as a colourless oil (160 mg, 76% yield).
