Reaction Steps

To a solution of methyl 2-([(2,4-difluorophenyl)methyl]oxy}-5-(4-morpholinylcarbonyl)benzoate (may be prepared as described in Description 110, 100 mg, 0.26 mmol) in tetrahydrofuran (THF) (4 ml) was added lithium hydroxide (26 mg, 1.09 mmol) and water (1 ml). The mixture was heated at 50° C. for one hour, cooled and 2M hydrochloric acid (0.54 ml, 1.09 mmol) was added. The solvent removed in vacuo and the residue was redissolved in N,N-dimethylformamide (4 ml). Diisopropylethylamine (0.09 ml, 0.51 mmol), 2-fluoro-3-pyridinamine (34.4 mg, 0.31 mmol) and HATU (243 mg, 0.64 mmol) were added and the mixture stirred overnight. The solvent was removed in vacuo and the residue purified by column chromatography (silicon, 10% methanol/dichloromethane) to give an oil. Purification by MDAP yielded the title compound as an off-white solid. 22 mg.
