Procedure

Tert-butyl 7-(aminomethyl)-1-cyclohexyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (999 mg) was dissolved in methylene chloride. Isobutyric acid (0.33 mL), triethylamine (1.2 mL), and O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1.32 g) were added thereto, followed by stirring at room temperature for 18 hours. Water was added to the mixture which was then extracted with chloroform. The extract was washed with a 1 M aqueous NaOH solution and saturated brine, and dried over magnesium sulfate. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography to obtain tert-butyl-1-cyclohexyl-7-[(isobutylamino)methyl]-3,4-dihydroisoquinoline-2(1H)-carboxylate (468 mg).
