production method	1. It is obtained by nitration, methoxylation and reduction of P-chlorotoluene. The mixed acid was added to p-chlorotoluene at 15-20 ℃, stirred at 30 ℃ for 2H, diluted with water, and the waste acid was separated and washed with water to obtain 4-chloro-3-nitrotoluene (yield: 30.6%). And 4-chloro-2-nitrotoluene (yield 56.7%), which were separated by fractional distillation and crystallization to give 4-chloro-3-nitrotoluene. It was reacted with methanol and sodium methoxide solution, and neutralized with sulfuric acid to give 3-nitro-4-methoxytoluene in 85.6% yield. After reduction with water, iron powder and formic acid, the solvent gasoline is extracted and distilled several times. 2. 2-nitro-4-cresol was obtained by nitration of p-cresol, then methylated with dimethyl sulfate to 3-nitro-4-p-methoxytoluene, and finally reduced with sulfide base. P-chloro-N,N-diethylbenzylamine was prepared by nitration, methoxylation and reduction.
