実験手順

A mixture of 450 mg (0.94 mmol) of N-[2-t-butyl-5-(aminomethyl)phenyl]-3-(2,4-dimethoxyphenyl)octanamide hydrochloride (prepared as described in Preparation 26B), 203 mg (2.50 mmol) of potassium cyanate, 30 ml of water and 1 ml of acetic acid was heated under reflux for 2 hours. At the end of this time, the reaction mixture was neutralized by adding sodium hydrogencarbonate, after which the mixture was extracted with ethyl acetate. The extract was washed several times with water and once with a saturated aqueous solution of sodium chloride, after which it was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and the resulting residue was purified by column chromatography through 37 g of silica gel using a 100:5 mixture of ethyl acetate and methanol as the eluent, to give a crystalline product. This product was recrystallized from a mixture of methylene chloride and hexane to give 273 mg of the title compound in a 60% yield, melting at 112-113° C. (from methylene chloride-methanol).
