Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 41789-95-1, name is 1-(3-Methoxyphenyl)-N-methylmethanamine, A new synthetic method of this compound is introduced below., HPLC of Formula: C9H13NO
Step C: To a solution of the acid (1.85 g, 7.6 mmol) from step B above and N-methyl morpholine (1.5 mL, 13.7 mmol) in dichloromethane (50 mL) at -20 C. was added isobutyl chloroformate (1.2 mL, 9.1 mmol) dropwise. The reaction solution was stirred at -20 C. for 45 minutes and then a solution of 3-(methoxybenzyl) methylamine (1.3 g, 8.4 mmol) in dichloromethane (10 mL) was added to it dropwise. The resultant solution was warmed to room temperature and stirred overnight. The reaction solution was then washed with water, saturated sodium bicarbonate and brine, dried over sodium sulfate and concentrated under reduced pressure. The crude product obtained was purified by flash column chromatography (95:5 to 50:50 hexanes/ethyl acetate) to give the desired product (2.0 g, 78%) as a yellow oil: 1H NMR (CDCl3, 500 MHz) delta 7.96-7.86 (m, 3H), 7.59-7.37 (m, 2H), 7.34-7.26 (m, 2H), 7.04-6.78 (m, 4H), 4.70 (d, J=13.5 Hz, 2H), 3.80 (s, 3H), 3.10 (d, J=17.9 Hz, 3H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
