実験手順

To a stirred solution of 350 mg (1.37 mmole) of the product from Example 140 in 10 mL dimethylformamide at 0° C. was added 60 mg (1.51 mmole) sodium hydride. The mixture was stirred at 0° C. for 30 minutes, then 349 mg (1.64 mmole) 2-(chloromethyl)-7-chloroquinoline was added. The mixture was warmed to room temperature and stirred for 72 hours. The mixture was poured into water and extracted with ethyl acetate. The ethyl acetate extract was washed with water and brine, dried (MgSO4) and concentrated to give an oil. Flash chromatography on silica gel eluting with 40% ethyl acetate in hexanes yielded 476 mg (81%) of the title product as a solid, mp 128°-130° C. Analysis calculated for C26H23N2O2Cl: C, 72.47; H, 5.38; N, 650. Found: C, 72.47; H, 5.12; N, 6.43.
