A color photosensitive material for magenta coupler intermediate and its preparation method (by machine translation)
This invention relates to a color photosensitive material for magenta coupler intermediate, having the formula (I) indicated by the structure, the preparation method is to 2 – [3 – (4 – tert-butyl phenyl) – 1H – 1, 2, 4 – triazole – 5 – yl] acetic acid and 2, 6 – di-tert-butyl – 4 – methyl cyclohexanol as a raw material, in toluene, xylene, ethyl acetate, cyclohexane, normal heptane and the like of the organic solvent in the system, in the acetic anhydride under the catalytic action of, 35 – 60 C reaction 1 – 4h after, make the 4 – methyl – 2, 6 – di-tert-butyl cyclohexanol {1 – acetyl – 3 – [4 – tert-butyl phenyl] – 1H – 1, 2, 4 – triazole – 5 – yl} acetate. The invention simple preparation process, the reaction condition is warm, less steps, time is short, low energy consumption, after treatment is simple, the final product of relatively high purity and yield, is very suitable for industrial large-scale production.
