Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 202197-26-0, name is 3-Chloro-4-((3-fluorobenzyl)oxy)aniline, This compound has unique chemical properties. The synthetic route is as follows., name: 3-Chloro-4-((3-fluorobenzyl)oxy)aniline
Step 2) N-(3-chloro-4-((3-fluorobenzyl)oxy)phenyl)-6-nitroquinazolin-4-amine A mixture of 4-chloro-6-nitroquinazoline (7.50 g, 35.8 mmol) and 3-chloro-4-((3-fluorobenzyl)oxy)aniline (9.00 g, 35.8 mmol) in isopropanol (150 mL) was heated to 80 C and stirred for 3.0 hours. The resulting mixture was then cooled to 20 C, and a yellow solid precipitated out. The mixture was filtered. The filter cake was washed with isopropanol (20 mL) and dried under vacuum to give the title compound as a yellow solid (8.50 g, 59.8%). The compound was characterized by the following spectroscopic data: MS (ESI, pos.ion) m/z : 425.8 [M+l]+; and NMR (400 MHz, CDC13) delta: 11.30 (brs, 1H), 9.54-9.48 (m, 1H), 8.45-8.41 (m, 1H), 8.31-8.25 (m, 1H), 7.98-7.89 (m, 1H), 7.50-7.47 (m, 1H), 7.35-7.26 (m, 1H), 7.05-6.96 (m, 1H), 6.90-6.80 (m, 2H), 7.74-7.60 (m, 2H), 4.84 (s, 2H).
According to the analysis of related databases, 202197-26-0, the application of this compound in the production field has become more and more popular.
