Versuchsvorschrift

A resealable pressure bottle was charged with 1,4-dichlorophthalazine (1258 mg, 6.28 mmol), decahydroisoquinoline (588 μl, 3.95 mmol), potassium carbonate (546 mg, 3.95 mmol) and DMSO (20 mL, 0.2 M). Reaction was stirred at 80° C. for 16 h, then cooled to RT and diluted with 5 mL of DMSO. The solution was purified by Gilson HPLC (10% to 90% CH3CN/H2O/0.1% TFA) to afford 1-chloro-4-(octahydroisoquinolin-2(1H)-yl)phthalazine. MS [M+H]=302.1. Calcd for C17H20ClN3: 301.8.
