    Abstract: PURPOSE: To obtain a new bisurea compound useful for producing a 1,3-dialkyl-2- imidazolidinone useful as an aprotic polar solvent and an intermediate for medicines and agricultural chemicals. CONSTITUTION: This bisurea compound of formula I (R is an alkyl). The compound is obtained by reacting an N,N',N"trialkyldiethylenetriamine of formula II with urea preferably at 100-155 deg.C, especially 120-145 deg.C. A 1,3-dialkyl-2- imidazolidinone of formula III can be obtained by thermally decomposing (especially preferably at 210-240 deg.C) the compound of formula I. The compound of formula II as a raw material is a by-product in producing an N,N'- dialkylethylenediamine from dichloroethane and an alkylamine in reaction for obtaining the compound of formula III from the N,N'-dialkylethylenediamine and urea. The compound has no main use, development of the use has been required and the compound is effectively utilized by this method.

    Abstract: PURPOSE: To obtain a 1,4-dialkyl-2,3-piperazinedione which is useful as a solvent and the like by reaction of a specific amine with an oxalate diester at a temp, lower than a specific temp, to achieve the improvement of the reaction yield and selectivity, simplified isolation of purified product and recovery and recycle of the reaction solvent. CONSTITUTION: The reaction of an N,N'-dialkylethylenediamine of formula I with an oxalic diester of formula II (R' is an alkyl) such as di-n-butyl oxalate is carried out at a temp lower than 130 deg.C (for example, at 25-130 deg.C) to give the objective compound of formula III. It is preferred that the reaction is effected in the presence of no solvent or in an alcohol same as that formed as a by-product during the reaction and after the target product is isolated, the recovered solvent is reused.

    Abstract: PURPOSE: To produce a carbamate-substituted salicylic acid derivative having high purity in a high yield by reacting a specific alkali metal salt of an aminosalicylic acid derivative with a specific haloformate compound in an alcoholic solvent. CONSTITUTION: A salicylic acid derivative of formula III is produced by reacting (A) an alkali metal salt of a compound of formula I (X1 and X2 are each H, an alkyl, an alkoxy, an aralkyl, an aryl or a halogen; R1 is H, an alkyl, an aralkyl or an aryl) with (B) a compound of formula II (Y1 and Y2 are each O or S; R2 ), is an alkyl, an alkenyl, an aralkyl or an aryl; Z is a halogen) in an alcoholic solvent. An example of the salicylic acid derivative is 4-(n- octyloxycarbonylamino)salicylic acid. The derivative is useful as an electron accepting compound (color developing agent) for recording materials such as heat-sensitive or pressure-sensitive recording materials, etc.
