    • The present invention lies in a process for producing a compound represented by the following formula nullIVnull, which comprises the following steps (1) to (3), as well as in an intermediate therefor. (1) A step which comprises reacting a compound represented by the following formula nullInull with a compound represented by the following formula nullVInull or with a mixture of a compound represented by the following formula nullVIInull and a compound represented by the following formula nullVIIInull to obtain a compound represented by the following formula nullIXnull, and hydrolyzing the compound represented by the formula nullIXnull under acidic conditions to obtain a compound represented by the following formula nullIInull. (2) A step which comprises reacting the compound represented by the formula nullIInull with hydroxylamine to obtain a compound represented by the following formula nullIIInull. (3) A step which comprises dehydrating the compound represented by the formula nullIIInull to obtain a compound represented by the formula nullIVnull. 1 null(R1)(R2)NnullCH(OR3)(OR4) nullnullnullVInull(CH3)2NnullCH(OCH3)2 nullnullnullVIInull(R1)(R2)NH nullnullnullVIIInull 2
