Reaction Steps

3-{2-Fluoro-6-[(5-fluoro-2-methoxy-pyridin-3-ylmethyl)-amino]-pyridin-3-ylmethyl}-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid methyl ester (P-1693, 1 equivalent) is slurried with methylamine (2N in methanol, 15 equivalents) in a sealable vial, sealed and heated at 50° C. overnight. Additional methylamine (2N in methanol, 15 equivalents) is added and heated at 50° C. overnight. The reaction is concentrated under vacuum, the residue dissolved in tetrahydrofuran for purification on a C18 reverse phase column, eluting with 0-100% methanol (with 10% tetrahydrofuran)/water. Appropriated fractions are combined and concentrated under vacuum. The resulting material is triturated with ethyl acetate/heptane and filtered, washing with heptane. The solid is dried under vacuum to provide the desired compound.
