実験手順

4-chloro-N,N-bis(4-methoxybenzyl)-2-oxo-1,2-dihydroquinoline-3-carboxamide (Example 74b) (4.25 g, 9.18 mmol) was dissolved in DMF (20 mL), and 4-methoxybenzylamine (2.68 mL, 20.6 mmol) was added. The reaction was heated at 100° C. for 1.5 hours, then cooled to room temperature and poured into ice water (300 mL). The resultant precipitate was collected by filtration and further chromatographed on silica gel (0% to 20% MeOH in dichloromethane) to give crude N,N-bis(4-methoxybenzyl)-4-(4-methoxybenzylamino)-2-oxo-1,2-dihydroquinoline-3-carboxamide (3.65 g, 71%), which was used without further purification. MS 564 (MH+).
