A process for the preparation of a 1-azolyl-3,3-dimethyl-1-phenoxybutan-2-ol of the formula ##STR1## in which X is a nitrogen atom or the CH group, Y is halogen, alkyl, alkoxycarbonyl, nitro or optionally substituted phenyl, and n is 0,1,2 or 3. comprising reacting a 1-azolyl-3,3-dimethyl-1-phenoxybutan-2-one of the formula ##STR2## with a secondary alcoholate under pressure in the presence of a diluent. Advantageously the reaction is carried out at a temperature about 20.degree. to 40.degree. C. above the boiling point of the diluent which is a secondary alcohol, the alcoholate is aluminum isopropylate and is present in about 0.35 to 0.4 mol per mol of ketone, and the reaction is carried out under an excess pressure of about 1.5 to 5 bar.
一种制备式为##STR1##的1-氮杂基-3,3-二甲基-1-苯氧基丁醇的方法,其中X是氮原子或CH基团,Y是卤素、烷基、烷氧羰基、硝基或可选择取代的苯基,n为0、1、2或3。包括在稀释剂存在下,在压力下将式为##STR2##的1-氮杂基-3,3-二甲基-1-苯氧基丁酮与次醇醇盐反应。优选在稀释剂的沸点上方约20°C至40°C的温度下进行反应,稀释剂为次醇,醇盐为异丙基铝醇盐,每摩尔酮含约0.35至0.4摩尔的异丙基铝醇盐,反应在约1.5至5巴的过量压力下进行。
