Adding a certain compound to certain chemical reactions, such as: 13726-14-2, name is 4-Chloro-3-methoxyaniline, belongs to chlorides-buliding-blocks compound, 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, Recommanded Product: 13726-14-2
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). NMR (400 MHz, DMSO-ifc) delta 10.27 (s, 1H), 8.81 (s, 1H), 7.48 (d, / = 2.3 Hz, 1H), 7.43 (d, / = 8.6 Hz, 1H), 7.28 (dd, / = 8.6, 2.3 Hz, 1H), 4.37 (q, / = 7.1 Hz, 2H), 3.85 (s, 3H), 1.34 (t, / = 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.
