Adding some certain compound to certain chemical reactions, such as: 13726-14-2, name is 4-Chloro-3-methoxyaniline, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 13726-14-2. 13726-14-2
Ethyl 2-chloro-4-(4-chloro-3-methoxyphenylamino)pyrimidine-5-carboxylate (RJ1- 061): A mixture of ethyl 2,4-dichloropyrimidine-5-carboxylate (0.442 g, 2.0 mmol), 4-chloro-3- methoxyaniline (0.331 g, 2.1 mmol), DIPEA (0.42 mL, 2.4 mmol), and iPrOH (2 mL) was added to a 5 mL microwave vial which was then sealed and placed in a hot oil bath with stirring at 85 C overnight for 17 hours. At this point, a brown solid had formed and this was then washed with iPrOH (10 mL), water (10 mL), iPrOH (10 mL), and hexanes (10 mL) to yield RJ1-061 as a brown solid (0.570 g, 83%). m.p. = 119 C (decomposed). XH NMR (400 MHz, DMSO-) delta 10.27 (s, 1H), 8.81 (s, 1H), 7.48 (d, J= 2.3 Hz, 1H), 7.43 (d, J= 8.6 Hz, 1H), 7.28 (dd, J= 8.6, 2.3 Hz, 1H), 4.37 (q, J= 7.1 Hz, 2H), 3.85 (s, 3H), 1.34 (t, J= 7.1 Hz, 3H). LRMS (ESI+) m/z 342.1 (MC135C135+H)+, 344.0 (MC135C137+H)+, 346.0 (MC137C137+H)+; (ESI-) m/z 339.3 (MC135C135-H)-; HRMS (ESI+) m/z calculated for C14H13CI2N3O3 (M+H)+ 342.04067, found 342.04100.
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 4-Chloro-3-methoxyaniline.
