実験手順

A solution of phthalic anhydride (14.81 g, 0.10 mole) and 6-amino-m-cresol (12.32 g, 0.10 mole) in 200 mL of acetic acid was stirred at ambient temperature for 30 minutes and then refluxed for 6 hours. The solution was cooled and poured into 500 mL ice-water with rapid stirring and the resultant solid was collected by suction filtration, washed with ice-cold water several times and air dried overnight to afford 24.1 g (95% yield) of product 1 as a light brown solid, mp 251-254° C. TLC (silica ; EtOAc), Rf =0.68.
