The synthesis of 1 - (bromomethyl) - 3 - fluoro - 5 - methoxybenzene has the following common paths.
First, 3 - fluoro - 5 - methoxybenzoic acid is used as the starting material. First, 3 - fluoro - 5 - methoxybenzoic acid is co-heated with dichlorosulfoxide to make it undergo an acyl chloride reaction to obtain 3 - fluoro - 5 - methoxybenzoyl chloride. Subsequently, using lithium tetrahydroaluminium as a reducing agent, 3-fluoro-5-methoxybenzoyl chloride is reduced at low temperature and in an anhydrous environment to obtain 3-fluoro-5-methoxybenzyl alcohol. Finally, 3-fluoro-5-methoxybenzyl alcohol is reacted with phosphorus tribromide at a suitable temperature to replace the hydroxyl group with a bromine atom to obtain 1- (bromomethyl) -3-fluoro-5-methoxybenzene. The reaction conditions of each step of this path are relatively mild, and the raw materials are relatively easy to obtain. However, some reagents such as lithium tetrahydroaluminium are active in nature and need to be handled carefully.
Second, 3-fluoro-5-methoxybenzaldehyde can be started from 3-fluoro-5-methoxybenzaldehyde. First, 3-fluoro-5-methoxybenzyl formaldehyde is reduced to 3-fluoro-5-methoxybenzyl alcohol using sodium borohydride as a reducing agent. Next, similar to the above method, phosphorus tribromide is used to react with it to complete the conversion of hydroxyl groups to bromomethyl groups to obtain the target product. Compared with lithium tetrahydride, sodium borohydride is slightly milder in nature and slightly safer in operation. However, during the reduction reaction, it is still necessary to pay attention to the control of the reaction conditions to prevent side reactions from occurring.
Third, 3-fluoro-5-methoxyaniline is used as the starting material. After the diazotization reaction, 3-fluoro-5-methoxyaniline is treated with sodium nitrite and hydrochloric acid to form a diazo salt. Subsequently, cuprous bromide is added, a Sandmeier reaction occurs, and bromine atoms are introduced. After that, the target molecular structure is gradually constructed through a series of methoxylation and other reactions. The steps of this method are relatively complicated, but it is also a feasible strategy for the situation where the specific raw materials are abundant. Each method has its own advantages and disadvantages, and the appropriate synthesis path should be selected after comprehensive consideration according to the actual situation, such as raw material cost, reaction equipment, operation difficulty and other factors.
