obtained by nitrating 8-bromomethylquinoline as described in [14]. Reaction of quinolines (IVa-h) with N-methylpropargylamine (V) in methanol in the presence of potassium carbonate gave the propynylated derivatives (IIa-h); in the case of (IIc) and (IIh), (V) was used as the solvent. Alkylation of 8-(N-methyl)aminomethyl-5-quinolinecarboxylic acid (VI) [13] with propargyl bromide in the presence of alkali
起始的 5-氯和 5-溴-8-甲基喹啉(IIIb 和 d)是通过 8-甲基喹啉在硫酸银存在下在浓硫酸中直接卤化制备的 [8]。7-~11oro-8-methylquinoline (IIIc) 由 Skraup 反应得到 [9],5-fluoro-8-methylquinoline (IIIa) 由 Baltz--Schiemann 反应 [i0, ii] 从 5-amino8-methylquinoline 得到[12]。如[8]和[13]中所述,获得腈(IIIe)、酯(IIIf和g)和8-溴甲基衍生物(IVa、b、dh)。7-Chloro-8-bromomethylquinoline (IVc) 和 5-nitro-8-bromomethylquinoline (IVh) 是通过用 N-溴代琥珀酰亚胺 (IIIc) 和 (IIIh) 溴化来合成的。硝基化合物 (IVh) 也可通过硝化 8-溴甲基喹啉获得,如
