Reaction Steps

1-cyclohexyl-3,4-dihydroisoquinoline-7-carboxylic acid (1.15 g) was dissolved in methylene chloride (15 mL). O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (2.03 g), N,N-diisopropylethylamine (1.55 mL), and 2-methyl-1-propanamine (0.87 mL) were added thereto, followed by stirring at room temperature for 18 hours. Then, water was added to the mixture, followed by extraction with chloroform. The extract was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography (chloroform-MeOH) to obtain 1-cyclohexyl-N-isobutyl-3,4-dihydroisoquinoline-7-carboxamide (700 mg).
