Versuchsvorschrift

To a two-layer solution of 3-amino-4-methylphenol (3.25 g, 26.4 mmol) in tetrahydrofuran (20 mL)/1N aqueous sodium hydrogencarbonate solution (39 mL) was added a solution of 3-(1-cyano-1-methylethyl)benzoyl chloride synthesized above in tetrahydrofuran (20 mL), and the mixture was stirred at room temperature for 3 hr. The aqueous layer was separated, and extracted with ethyl acetate (100 mL). The combined organic layer was washed with 5% aqueous sodium hydrogencarbonate solution (50 mL) and saturated brine (50 mL), successively, and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was recrystallized from ethyl acetate (45 mL)/hexane (45 mL) to give the title compound (5.95 g, 77%) as a colorless powder.
