실험 절차

4-Chloro-5-fluoro-1H-pyrrolo[2,3-b]pyridine can be obtained as in example 4 stage 4(b) but starting from 1.7 g of 5-fluoro-1H-pyrrolo[2,3-b]pyridine 7-oxide in 10 cm3 of phosphorus oxychloride. In this way, 1.3 g of 4-chloro-5-fluoro-1H-pyrrolo[2,3-b]pyridine is obtained as a solid with the following characteristics:
