Reaction Steps

A mixture of 4-chloro-2-methyl-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (4.73 g), potassium carbonate (6.4 g), methanol (45 ml), and water (15 ml) was stirred at 90° C. for 2 hours. After the mixture was cooled, the obtained needle crystals were filtered and washed with water to obtain 4-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (1.85 g).
