실험 절차

In a manner analogous to that of example 1(b), 8-bromo-octanoic acid benzyloxy-amide (example 1(a); 0.3 g, 1.3 mmol) was reacted with 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline hydrochloride (0.43 g, 1.3 mmol) in the presence of potassium carbonate (0.18 g, 1.4 mmol) and DMF as solvent to give 8-(6,7-dimethoxy-3,4-dihydro-1H-isoquinolin-2-yl)-octanoic acid benzyloxyamide as an almost colorless wax (yield 0.28 g, 49%; purified by column chromatography using silica gel and ethyl acetate: methanol 9:1 as an eluent). MS (M+H+)=441.
