実験手順

1.44 g of a 50% dispersion of sodium hydride in mineral oil was added to a solution of 3.69 g (0.010 mol) N-(2-chloro-3-pyridinyl)-2-[[(4-methoxyphenyl)methyl]amino]-3-pyridinecarboxamide in 100 ml of dimethylformamide. After the evolution of hydrogen stopped, the mixture was heated (110° C.) for 16 hours and then refluxed for eight hours. After the mixture had cooled, the excess sodium hydride was decomposed by the slow addition of ice. The mixture was further diluted with water, and the product was extracted with ether and concentrated. The crystallized residue was filtered and washed with ether to give 1.60 g of 5,11-dihydro-11-[(4-methoxyphenyl)methyl]-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (50% of theory) as an off-white powder, m.p. 209°-210° C.
