Reaction Steps

By proceeding in a similar manner but substituting an equimolecular quantity of 1-methoxycarbonyl-3-(2-amino-4-isopropoxycarbonylaminophenyl)thiourea and 1-ethoxycarbonyl-3-(2-amino-4-isopropoxycarbonylaminophenyl)thiourea for 1-methoxycarbonyl-3-(2-amino-4-n-butylphenyl)thiourea, there were obtained 1-methoxycarbonyl-3-(2-acetamido-4-isopropoxycarbonylaminophenyl)thiourea, m.p. 187°-188° C. (with decomposition) and 1-ethoxycarbonyl-3-(2-acetamido-4-isopropoxycarbonylaminophenyl)thiourea, m.p. 201°-202° C. (with decomposition), respectively.
