Abstract
2-Para-aminobenzenesulphonamidopyrimidine is prepared by reacting p-aminobenzenesulphonyl guanidine with an acetal of b -alkoxyacrolein. Suitable acetals are the diethyl acetal, the dimethyl acetal of b -ethoxyacrolein, and also the acetals of b -methoxyacrolein and b -propyloxy-acrolein. In an example, b -ethoxyacrolein diethyl acetal is heated with p-aminobenzenesulphonyl-guanidine in amyl alcohol-glacial acetic acid solution. The ethyl alcohol liberated is evaporated off and the residue extracted with aqueous caustic soda. On acidification, crude 2-p-aminobenzenesulphonamidopyrimidine separated and is purified by recrystallisation. Specification 552,887 is referred to.
