yridine with manganese dioxide yielded the corresponding aldehyde, the condensation of which with diethyl bromomalonate furnished hydroxydihydrofuro[3,2-b]pyridinediearboxylie acid ester. Saponification of the diester with concentrated hydrochloric acid afforded the hydrochloride of 5-methylfuro[3,2-b]pyrjdine car-boxylic acid.
用二氧化锰氧化3-羟基-6-甲基-2-羟基甲基吡啶得到相应的醛,该醛与溴丙二酸二乙酯缩合,得到羟基二氢呋喃[3,2- b ]吡啶二联羧酸酯。用浓盐酸将二酯皂化,得到5-甲基呋喃并[3,2- b ]吡啶基羧酸的盐酸盐。
