Procedure

A solution of 3-carboxymethylcinnamic acid (427 g) (Example 2(a)) in dimethyl formamide (4.25 l) and aqueous ammonia (specific gravity 0.88, 8.5 l) was stored at room temperature for 4 days, concentrated to call 11 l, and then treated with ice (8 kg) and concentrated hydrochloric acid (1 l). The precipitated title product was washed with water and dried, m.p. >260° C.
