Summary:PROBLEM TO BE SOLVED: To obtain the subject compound useful as an intermediate for medical and an agricultural chemicals from an easily available or reusable material in a high purity and a high yield by reacting 3- or 4-dichloromethylbenzonitrile with morpholine and then hydrolyzing the obtained product. SOLUTION: This method is to react (A) 3- or 4-dichloromethylbenzonitrile (e.g. the product obtained by chlorinating a side chain of m- or p-toluyl chloride, purifying the resulted 3- or 4-methylbenzoyl chloride by rectification, converting it by amidation with an aqueous ammonia to 3- or 4-dichloromethylbenzamide and then dehydrating it with thionyl chloride or acetic anhydride) with (B) morpholine to obtain 3- or 4-dimorphlinomethylbenzonitrile and then hydrolyze it.
