Abstract:
There are provided a method for producing 2,4-disubstituted pyrimidine-5-ol, and particularly, 2,4-dimethylpyrimidine-5-ol and an intermediate thereof used in industrial production. The production method according to the present invention includes a step of producing 2,4-disubstituted pyrimidine-5-ol according to a hydrolysis reaction of a 2,4-disubstituted-5-(4-(nitrophenyl)oxy)pyrimidine compound and is suitable for industrial production since an inexpensive and easily available starting material can be used, regioselectivity of a substituent group is easily controlled, impurities are easily controlled, and 2,4-disubstituted pyrimidine-5-ol can be produced without using reagents and intermediates causing health problems, risks and the like.
