| abstract | 1338265 2-(2-Hydroxyphenyl) benzotriazoles FUJI PHOTO FILM CO Ltd 12 Oct 1971 [13 Oct 1970] 47548/71 Heading C2C [Also in Division G2] The compound of the formula where R<SP>1</SP> is methyl and R<SP>2</SP> is sec-butyl is made by diazotizing o-nitroaniline and coupling with omethyl-p-sec-butyl-phenol, the red oil obtained then being reduced with Zn/NaOH. Compounds where R<SP>1</SP> is sec-amyl and R<SP>2</SP> is methyl, or where R<SP>1</SP> is sec-butyl and R<SP>2</SP> is tertbutyl or sec-butyl are similarly made by using the appropriately substituted phenol. |
