| abstract | NEW MATERIAL:The compound of formula I (X is halogen; R is lower alkyl). n EXAMPLE: 2-N,N-diacetylamino-6-acetoxy-3,5-dibromophenylacetaldehyde. n USE: A precursor of 4-hydroxyindole useful as a synthetic raw material of pharmaceuticals, dyes and agricultural chemicals. n PREPARATION: The compound of formula I can be prepared by the ozone oxidation and reduction of the novel compound of formula II. The compound of formula II is produced by acylating m-aminophenol with acid anhydride, etc., halogenating to the novel compound of formula III (R is other than methyl), reacting the compound of formula III with the allyl halide of formula IV (X' is halogen) to obtain the novel compound of formula V, and finally heating the compound in the presence of an acid anhydride having a boiling point of ≥170°C (e.g. caproic anhydride). n COPYRIGHT: (C)1986,JPO&Japio |
