First take o-mercaptobenzoic acid as the starting material, in the ancient method, when in a suitable reaction kettle, add an appropriate amount of dehydrating agent, such as acetic anhydride and the like, heat to promote its molecular cyclization reaction to obtain benzo [b] thiophene-2 - formic acid. This step needs to pay attention to the control of temperature. If the temperature is too high, side reactions will occur, and if it is too low, the reaction will be slow and take a long time.
Then, the obtained benzo [b] thiophene-2-formic acid is carefully reduced in an alcohol solvent at low temperature with a hydride reducing agent, such as sodium borohydride. In the meantime, the choice of solvent is very critical, and it is necessary to choose the one with good solubility and stable chemical properties of the reducing agent and product. During the reaction, the reaction process needs to be closely observed to prevent excessive reduction. In this way, the carboxyl group can be converted into hydroxymethyl, and finally 2 - (hydroxymethyl) benzo [b] thiophene can be obtained.
Another method is to use o-benzyl bromide and thioacetamide as starting materials. First, the o-benzyl bromide and thioacetamide are reacted in an alkaline environment to form an intermediate. In this process, the strength of alkalinity and the length of the reaction time all have a great impact on the reaction. Then, the intermediate can also obtain the target product through hydrolysis, cyclization and other steps. When hydrolyzing, appropriate acid and base conditions need to be selected to ensure complete hydrolysis and not destroy the molecular structure. The cyclization step also needs to consider the reaction conditions to promote the smooth cyclization of the molecule to obtain 2- (hydroxymethyl) benzo [b] thiophene.
