Procedure

3-(2-Methylanilino)propionic acid is prepared in a manner similar to that described in Example 1, but starting from o-toluidine (64.3 g; 0.60 mol), acrylic acid (11.6 g; 0.16 mol) and water (36.6 cc). A white powder (23.85 g) is thus obtained which, after recrystallisation in a toluene/hexane mixture (70:30 by volume), gives a pure product (21.7 g; 0.12 mol), m.p. 87° C.
