Description 10 4-bromo-2-methyl-1W-pyrrolo[2,3-b]pyridine To a solution of 4-bromo-2-methyl-1 -(phenylsulfonyl)-1 H-pyrrolo[2,3-5]pyridine (D9) (16 g, 0.045 mol) in 1 ,4 dioxane (320 mL) was added 2M aqueous sodium hydroxide (114 rmL, 0.228 mol).The reaction was heated to 6O0C for 16 h. The reaction was cooled to ambient temperature. The organic layer was separated and the aqueous extracted with ethylacetate. The combined organics were washed with brine and dried over magnesium sulphate, filtered and concentrated in vacuo to give the title compound as a cream solid (10.07 g, 104%) LC/MS (Method B): MH+ 21 1/213 seen at retention time 1.04 mins.
