| abstract | PURPOSE: To prepare the subject compound in a high yield under a relatively mild condition by employing an N-substituted cyclic amide or N-substituted urea as a catalyst when a hydroxyethyl ether is made to react with thionyl chloride to prepare the subject compound. n CONSTITUTION: A compound of formula (R is alkyl or aryl which can have substituents, respectively) is allowed to react with thionyl chloride in the presence of an N-substituted cyclic amide [especially having amide bonds of formula II or III (R 1 is hydrocarbon group)] or an N-substituted urea such as N,N- dimethylimidazolidinone, N-methylpyrrolidone or N,N'-diphenyl urea preferably at 40-150°C, especially at 50-90°C, to prepare the objective compound of formula useful as an intermediate for drugs, agricultural chemicals, pigments, etc., under a relatively mild condition in a high yield, while reducing the production of 1,2-dichloroethane (by-product to below 1%. n COPYRIGHT: (C)1992,JPO&Japio |
