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. 37052-78-1, name is 5-Methoxy-1H-benzo[d]imidazole-2-thiol, A new synthetic method of this compound is introduced below., COA of Formula: C8H8N2OS
Reference Example 12 Production of 4-(5-methoxybenzimidazole-2-ylthio)butanoate ester hydrogen bromide salt 6.48 g (33.2 mmol) of 4-bromobutanoate ethyl ester were added to 10 ml of an ethanol solution containing 5.0 g (27.7 mmol) of 5-methoxybenzimidazole-2-thiol followed by stirring for 1 hour at 80 C. and adding 90 ml of ethyl acetate. The reaction solution was returned to room temperature and the formed crystals were filtered out followed by drying to obtain 9.34 g of the target compound (yield: 90%). 1H-NMR (270 MHz, CDCl3) (ppm): 7.65 (d, 1H, J=8.91 Hz), 7.24 (s, 1H), 7.00 (dd, 1H, J=2.43, 8.91 Hz), 4.21 (q, 2H, J=7.29 Hz), 3.83 (s, 3H), 3.74 (m, 2H), 2.61 (m, 2H), 2.10 (m, 2H), 1.30 (t, 3H, J=7.29 Hz)
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.
