Twenty-five title compds. (I; R = lower alkyl, alkenyl, benzyl) useful as intermediates for medicine, were prepd. by reaction of alkali aminophenolate(II; M = alkali metal) and III(X = halo) in the presence of alkali metal hydroxide and quaternary ammonium or phosphonium salt. Thus, 13.1 g II(M = Na), 2 g NaOH, 50 g III(R = Me2CH), 1.68 g(n-C5H11)4N+Cl- in 100 ml PhCl reacted for 10 hr at 60≦̸C to give 14.9 g I(b.p., 119≦̸C/10 mmHg; yield 98%).
