Reaction Steps

See FIG. 19(c). 1-((5-fluoro-2-methoxypyridin-3-yl)methyl)-6-methyl-1H-pyrrolo[3,2-b]pyridine-3-carboxylic acid (60 mg, 0.19 mmol) and 2-fluoroethanamine (21.60 mg, 0.34 mmol), TEA (0.080 mL, 0.57 mmol) was added. After 3 min1-Propanephosphonic acid cyclic anhydride (151 mg, 0.48 mmol) was added. The resulting reaction mixture was stirred at rt for 50 min. LCMS analysis showed formation of required product. Reaction was diluted with DCM and water.DCM layer was extracted and washed with brine and dried over sodium sulphate and concentrated. Purification was done on Waters RP system to get product 1-((5-fluoro-2-methoxypyridin-3-yl)methyl)-N-(2-fluoroethyl)-6-methyl-1H-pyrrolo[3,2-b]pyridine-3-carboxamide (25.00 mg, 36.5%).
