合成路线1
该中间体在本合成路线中的序号：(IV)The intermediate 2-chloropyridin-3-ylmethylamine (VI) has been obtained as follows. The reaction of 2-chloropyridine-3-carboxylic acid (I) with refluxing SOCl2 gives the corresponding acyl chloride (II), which is reduced by means of NaBH4 in water to yield the carbinol (III). The reaction of (III) with SOCl2 in toluene affords the chloromethyl derivative (IV), which is treated with esther NaN3 in DMF or LiN3 ijn DMSO to provide the azidomethyl derivative (V). Finally, this compound is reduced with PPh3 in THF/water or H2, Pd/C in EtOH to furnish the desired 2-chloropyridin-3-ylmethylamine intermediate (VI).
