Procedure

Commercially available 1,2,3,4-tetrahydroisoquinoline (50 mg) was dissolved in chloroform (10 ml), and triphosgene (111 mg) was added to the solution. The mixture was stirred at room temperature for 2 hr. The solvent was removed by distillation to give 1,2,3,4-tetrahydro-2-isoquinolinecarbonyl chloride. 1,2,3,4-Tetrahydro-2-isoquinolinecarbonyl isothiocyanate was prepared using this compound as a starting compound according to the description of the literature. 4-[(6,7-Dimethoxy-4-quinolyl)oxy]aniline (50 mg) was dissolved in toluene (5 ml) and ethanol (1 ml) to prepare a solution. A solution of 1,2,3,4-tetrahydro-2-isoquinolinecarbonyl isothiocyanate in ethanol (1 ml) was then added to the solution, and the mixture was stirred at room temperature for 2 hr. The reaction solution was concentrated, and the residue was purified by chromatography on silica gel using chloroform/acetone for development to give the title compound (78 mg, yield 94%).
