Synthesis
methyl 6-(bromomethyl)nicotinate is synthesised using methyl 6-methylnicotinate as a raw material by chemical reaction. The specific synthesis steps are as follows:
0.471 g (1.0 equivalent) of N-bromosuccinimide and 64 mg (0.1 equivalent) of benzoyl peroxide are added to a solution of 0.4 g of the product obtained in the preceding Stage 1 in 15 ml of carbon tetrachloride. The solution is brought to reflux for 6 hours, then filtered and evaporated under reduced pressure. The residue is purified by chromatography on silica gel (dichloromethane/ethyl acetate: 95/5) to produce 0.262 g of the expected product. [ Yield: 43percent MS: MH+ 231].
