| Abstract: | Furo3,2-c] pyridine (I) was nitrated to give 2-nitrofuro3,2-c]pyridine (II). Bromination and chlorination of I gave, respectively, 2,3-dibromo-2,3-dihydrofuro3,2-c]pyridine (III) and 2,3-dichloro-2,3-dihydrofuro3,2-c]pyridine (IV). Oxidation of I with hydrogen peroxide afforded furo3,2-c]pyridine 5-oxide (V) which was converted to I by phosphorus trichloride and to 4-chlorofuro3,2-c]pyridine (VI) by phosphorus oxychloride. |
