Title compds. (I; R1,R2,R3 = same or different H, Me, MeO, Cl; R4 = H, C1-4 alkyl; R5 = C1-6 alkyl, benzyl; R6 = C1-4 alkyl, benzyl; n = 0,1) useful as fungicides, were prepd. by reaction of II and III. Thus, 34 g II(R1,R2,R3 = MeO; R4 = H, n = o) and 97.2 g III(R5 = Me; R6 = Et) were suspended in 240 ml dimethyl formamide and 1 ml conc. HCl and stirred for 4 hr at 80-90≦̸C to give 35.2 g I(m.p., 142-144≦̸C; yield 81.5%).
