実験手順

To a solution of tert-butyl[(6-{[3-(aminocarbonyl)-5-(4-fluorophenyl)-2-thienyl]amino}pyridin-2-yl)methyl]methylcarbamate (90 mg, 0.197 mmol) in dichloromethane (0.4 mL) was added trifluoroacetic acid (0.4 mL) and the reaction was maintained at room temperature for 1 hour. The volatiles were removed in vacuo and the crude product was purified by reverse phase HPLC (20-90% acetonitrile/water with 0.05% trifluoroacetic acid). The appropriate fractions were diluted with ethyl acetate (50 mL) and saturated aqueous sodium bicarbonate (40 mL). The layers were separated and the organic layer was washed with saturated aqueous sodium bicarbonate (40 mL) and water (2×40 mL), dried over sodium sulfate, filtered and concentrated to yield the title compound.
