Procedure

To a suspension of 1.5 g of 1,5-bis(3-amino-4-hydroxyphenyl)pentane (0.0052 mol) in 7 ml of isobutyl methyl ketone was added 1.05 g (0.0125 mole) of sodium bicarbonate and 5 ml of water. The suspension was stirred in an ice bath and 1.4 g (0.0124 mole) of chloroacetyl chloride was added dropwise. After addition, the mixture was allowed to come to room temperature and then was refluxed for 4 hours. After cooling, the resulting crystalline solid was filtered and washed with acetone to yield 0.4 g of off-white product of m.p. 189°-190° C.
