Reaction Steps

A mixture of 40 ml of 98% diethylamine, 44.3 mg (0.25 mmole) of palladium chloride, 131.2 mg (0.5 mmole) of triphenylphosphine, 47.6 mg (0.25 mmole) of cuprous iodide, 3.5 g (10.5 mmole) of 8-chloro-5-bromo-1-phenyl-3H-2-benzazepine and 5 ml of propargyl alcohol was stirred at room temperature under nitrogen for 7 hr. The mixture was concentrated at reduced pressure to dryness. The residue was dissolved in methylene chloride, and washed with water. The methylene chloride solution was dried over anhyrous sodium sulfate and concentrated at reduced pressure to dryness. Purification by column chromatography (silica gel, 20 g; eluent 20% ether in methylene chloride) gave a colorless oil. The oil was dissolved in an excess of methanolic hydrogen chloride and concentrated at reduced pressure to dryness. The residue crystallized from a mixture of methanol and ether to give a tan solid, mp 228°-229° C. dec.
