Abstract: PURPOSE:To obtain the title compound which is an intermediate for medicines in simple procedures in high yield, by treating a specific compound, readily prepared through addition reaction between 2-amino-cyclohexanone oxime and a thioisocyanate, with an acidic substance. CONSTITUTION:A N-(2-hydroxyimino-cyclohexyl)-thiourea of formula I: (R is alkyl, allyl, or aralkyl group) is brought into contact with an acidic substance, e.g. hydrogen chloride, hydrogen bromide, sulfuric or benzenesulfonic acid, at 0- 150 deg.C, preferably 10-100 deg.C to give the objective compound of formula II. The thiourea of formula I is obtained by addition reaction of 2-amino-cyclohexanone oxime with a thiocyanate of formula IV according to the well-known method. Preferably, the amount of the acidic substance is 0.01 mole or more per mole of the compound of formula I.
