    摘要: PURPOSE:To safely obtain the subject compound useful as an intermediate for producing medicines, agrochemicals, etc., at a low cost by hydrolyzing specific acetamides in the presence of a base. CONSTITUTION:Acetamides of formula I [X is halogen, lower-haloalkyl or lower-haloalkoxy; R is lower alkyl; (n) is 0-3] are hydrolyzed in the presence of a base such as sodium hydroxide to provide the objective compound of formula II. Furthermore, the base is used in an amount of 2-5mol based on 1mol acetamide of formula I and the hydrolytic temperature is preferably 100-200 deg.C.
