実験手順

A solution of diethyl(2-{4-[(3-chloro-4-fluorophenyl)amino]-5,8-dihydropyrido[4′,3′:4,5]thieno[2,3-d]-pyrimidin-7(6H)-yl}-2-oxoethyl)phosphonate from Example 13A (644 mg, 1.26 mmol) in THF (2.5 mL) was cooled to −78° C. Sodium hydride (60% in mineral oil, 50 mg, 1.26 mmol) was added, and the mixture was stirred for 15 min. Subsequently, a solution of tert-butyl (2S)-2-formylpyrrolidine-1-carboxylate (250 mg, 1.26 mmol) in THF (2.5 mL) was added dropwise. The mixture was slowly warmed to rt and stirred overnight. Methanol was added, and the solvent was removed in vacuo. The crude product was purified by preparative HPLC, and the title compound crystallized from PE/MTBE to yield 397 mg (56%).
