Some common heterocyclic compound, 1535-75-7, name is 2-(Trifluoromethoxy)aniline, molecular formula is C7H6F3NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 2-(Trifluoromethoxy)aniline
Synthesis Example 32 Synthesis of 2-Trifluoromethoxybenzenesulfonamide [Compound (III-12)] Using 2-trifluoromethoxyaniline [Compound (XXV-12)] (5 g, 0.0282 mmol), 7.3 g (percent yield: 99.4%) of 2-trifluoromethoxybenzenesulfonyl chloride [Compound (XXII-12)] was synthesised according to the process of Synthesis Example 31 (3). Thereafter, the compound (III-12) was synthesised using 3.9 g (0.0149 mol) of the Compound (XXII-12) according to Synthesis Example 31 (3). White solid, m.p.: 183-184 C., yield: 2.09 g, percent yield: 46.2%. IR KBr cm-1: 3382, 3268, 1482, 1344, 1230, 1164, 768. 1H-NMR (60 MHz, d6-DMSO, delta): 7.2-7.65 (5H, m, aromatic ring H*3, NH2), 7.86 (1H, dd, J=2Hx, 8 Hz, aromatic ring H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1535-75-7, its application will become more common.
