Title compds.(IV); R'=alkyl, cycloalkyl, haloalkyl, alkoxyalkyl; R"=alkyl, cycloalkyl, monohaloalkyl, alkoxyalkyl) were denitrosoated by treating with ketone (II; Ra=lower alkyl, Ph, substituted Ph; R6=lower alkyl) at 20-120≦̸C in the presence of HCI or HBr and, optionally, an inert organic solvent. Thus, 96g of a soln. contg. 38.2wt.% N-(1-ethyl-propyl)-2, 6-dinitro-3, 4,-xylidine and 13.4wt.% N-(1-ethyl-propyl)-N-nitro-2, 6-dinitro-3, 4-xylidine was added in 14.7g concd. HCI and 2.5g Et2CO, and the mixt. was heated 4 hr at 80-85≦̸C to give 51.4g solid product.
