合成路线1
该中间体在本合成路线中的序号：(III)2-Indolecarboxylic acid (I) was esterified with MeOH and SOCl2 to provide methyl ester (II). Subsequent N-alkylation of (II) using methyl iodide and NaH afforded N-methyl indole (III). Guanidine, liberated by treatment of the hydrochloride salt with NaOMe, was finally condensed with indole ester (III) at 130 C to produce the corresponding acylguanidine, which was isolated as the mesylate salt.
