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. 2106-04-9, name is 3-Chloro-2-fluoroaniline, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C6H5ClFN
Step 7. Preparation of compound (I). 2-[4-(5-cyano-4-{ [(dimethylamino)methylene] amino } -2-methoxyphenoxy)piperidin- 1 -yl] -JV-methylacetamide (compound (II),; 7.00 g, 17.71 mmoles), was suspended in methoxybenzene (35.8 g). Acetic acid (16.6 g) was charged and to the resulting solution was added 3-chloro-2-fluoroaniline (2.71 g, 18.07 mmoles). The reaction mixture was heated at 90 0C for 20 hours then cooled to 200C. Water (37.04 g) was charged to the reaction mixture, and the organic layer discarded. To the resulting aqueous mixture was charged isopropanol (39.00 g), followed by aqueous ammonia (20.79 g, 25%). The reaction mixture was heated to 30 0C and seeded with compound (I), which induced crystallisation. The reaction was then cooled to 00C and the product isolated by filtration. The filter cake was washed twice with a mixture of water (7.28 g) and isopropanol (4.68 g), then dried to afford the compound (I) (5.65 g, 55% yield); 1H NMR (400 MHz, DMSO-J6) delta ppm 1.79 (m, 2 H) 2.04 (m, 2 H) 2.38 (m, 2 H) 2.62 (d, J=4.5 Hz, 3 H) 2.74 (m, 2 H) 2.94 (s, 2 H) 3.93 (s, 3 H) 4.56 (tt, J=8.1, 3.8 Hz, 1 H) 7.21 (s, 1 H) 7.28 (m, 1 H) 7.50 (m, 2 H) 7.73 (q, J=4.5 Hz, 1 H) 7.81 (s, 1 H) 8.36 (s, 1 H) 9.56 (br.s, 1 H); Mass Spectrum: m/z (M + H)+ 474.2, 476.2.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2106-04-9.
