To a mixture of 7-hydroxy-1,2,3,4-tetrahydroisoquinoline-2-carboxylic acid tert-butyl ester (389 mg) and 4-hydroxymethyl-1-(pyridin-4-yl)piperidine (300 mg) in tetrahydrofuran (15 ml) and methylene chloride (5 ml) were added triphenylphosphine (450 mg) and diisopropyl azodicarboxylate (0.34 ml) and the mixture was stirred at room temperature for 24 hours. After completion of the reaction, the reaction mixture was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane:acetone=3:2-1:1, 1% triethylamine) and dried under reduced pressure to give the title compound (500 mg).
