INSTRUCTIONS (/) [Application Fields of the Invention] The present invention relates to a method for producing 8-hydroxyindole (8-hydr〇xyjiilolidine) and the like: 2 wherein 'R1 and R2 represents a substituent such as a hydrogen atom, a dentate, a hydroxyl group or an alkyl group; [Background of the Invention] The coumarin of the Ministry of Economic Affairs, the Intellectual Property Bureau employee consumption cooperative, has a high quantum yield due to the small overlap of absorption and emission spectra. The high molar absorption constant, with an unusual tuning wavelength range, is one of the most commonly used laser dyes and can be used as an indicator of biometric fluorescence. The 7-amino based rigid molecule is immobilized by a cycloalkylation process according to the techniques disclosed in U.S. Patent No. 3,873,940, U.S. Patent No. 3,932,415, U.S. Patent No. 4,005,092, U.S. Patent No. 4,471,041, U.S. Patent No. 4,736,032, and U.S. Patent No. 4,794,184, It will greatly increase the dipole moment and reduce the energy loss caused by the rotation of the amine group. This increases the fluorescence quantum yield of the coumarin laser dye, thereby greatly improving the luminescent efficacy of the laser dye. The method of making 8-base Zhulu Lijun and 8,10-two light-based Zhululi bite is reported. 3 The paper size is applicable to the Chinese National Standard (CNs) μ specification (210X297 mm) Ϊ287009 A7 B7 V. Invention Description (>) According to US Patent 4,005,092 ' US Patent 4,471,041 and Jbwrwa/ CAemiy/7 1987 52 Volume 1465 -1468 pages and other conventional inventions and literatures, all from 3-anthoxyaniline (m-anisidine) or 3,5-dimethoxyaniline (3,5-dimethoxyaniline) with a large amount of 1-bromo- 3-chloropropane (l-bromo-3-chloropropane) is obtained by subjecting a cycloalkylation reaction to removal of a methyl group with a strong acid. To obtain 3 methoxyaniline or 3,5-dimethoxyaniline, usually by 3-aminophenol or 3,5-dihydroxyaniline (3,5-dihydroxyaniline) The methylation reaction is carried out by dimethyl sulfate.
