Reaction Steps

A mixture of 4-aminobenzoic acid (1.37 g. 0.01 mole), 2-chloro-N,N-diethylacetamide 2.0 ml, 0.015 mole) and 1.8-diazabicyclo[5.4.0]-undec-7-ene (1.52 g, 0.01 mole) in benzene (20 ml) was stirred at 80° C. for 4 h and then evaporated in vacuo. The residue was taken up in ethyl acetate. After washing with 5% sodium bicarbonate and water the ethyl acetate extract was dried and evaporated in vacuo leaving crude title compound. Recrystallization from ethanol-water gave 1.5 g (60%). Mp 135°-136° C.
