Abstract
A process for the preparation of 4-carbamoxymethyl-1-phthalazone derivatives that are represented by the general formula I: **(See formula)** wherein R1 signifies a hydrogen atom or an alcoholic group, R2 signifies a hydrogen atom, an alcoholic group that can be branched or cyclic, or an alkenyl, aryl, aralcoyl, dialkoxylaminoalcoyl, furfuryl, picolyl or pyridyl group, R3 means a hydrogen atom, an alcoholic group, aryl, carbamoyl, N-alcoholcarbamoyl, NN-dialkoylcarbarmoyl, alcoholylsulfonyl, or arylsulfonyl, R4 means a hydrogen or halogen atom, an alcoholic or alkoxy group, R5 means a hydrogen atom or of halogen, an alcoholic, alkoxy, amino, acylamino, alkoxycarhonyl, or carbamoyl group, and R1 may together with R2 form a divalent alcoholic group which may be interrupted by a heteroatom, and R4 and R5 may be present at either position C-5, C-6, C-7 or C-8 of the phthalazone nucleus, characterized in that a compound of general formula II is reacted **(See formula)** wherein R3, R4 and R5 have the same meanings described with respect to formula I, with a compound of general formula III: **(See formula)** wherein R1 and R2 have the same meanings as described in formula I, and Y signifies a halogen atom, or an alkoxy, aryloxy, alcoholyl or arylthio group.
