Reaction Steps

30.2 g of 4-aminophenol was dissolved in 130 ml of N,N-dimethylformamide, followed by the addition of 11.64 g of 57% NaH and agitated at room temperature for 30 rain to obtain a N,N-dimethylformamide solution. 130 ml of toluene and 10.5 g of 57% NaH were added to 41 g of 4-hydroxy ethylbenzoate. After agitation, 45 g of N-phenyl chloroacetamide and 8.7 ml of N,N-dimethylformamide were also added. The toluene recovered from the reflux was reacted with the above N,N-dimethylformamide solution. After that, the N,N-dimethylformamide was recovered and extracted with toluene. 47 g of ethyl 4-phenylaminobenzoate was obtained when the toluene layer of the extraction process was dehydrated with magnesium sulfate. The product yield was 79%.
