実験手順

A mixture of compound 1d (5.0 g, 21 mmol) and NaH (2.5 g, 64 mmol) in anhydrous THF (300 mL) was stirred at rt for 10 min. 2-Chloroquinoline (4.2 g, 25 mmol) was then added and the mixture was heated to 70° C. for 5 h. The reaction was quenched with brine (300 mL) and extracted with EtOAc (2×500 mL). The organic layer was washed with brine (300 mL), dried over Na2SO4 and concentrated under reduced pressure. The residue obtained was recrystallized with hot EtOAc-hexanes to give compound 31a. Mass Spectrum (LCMS, ESI pos.): Calcd. for C20H19N5O2: 362.1 (M+H). found: 362.2.
