Conditions

Temperature: 80 °C

Procedure

A mixture of 6, 7-dimethoxy-1-phenyl-1,2,3,4-tetrahydroisoquinoline hydrochloride (160, 153 mg, 0.5 mmol), N-(1-fluorobenzyl)-N-indan-2-yl-2-bromoacetamide (161, 180 mg, 0.5 mmol) and potassium carbonate (500 mg) in acetonitrile is heated at 80° C. overnight. After cooling, the mixture is filtered and concentrated. The resulting residue is purified by column chromatography eluting with 5% methanol in chloroform to provide the title product (162) as a thick oil (215 mg, 78%). 1H NMR (CDCl3) 6.8-7.3 (m, 14H), 6.60(s, 1H), 6.05 (s, 1H),
