Reaction Steps
A mixture of 1.2 g (0.0032 mole) of 8-(2-chloroethoxy)-5-(2-chlorophenyl)-7-cyano-1,3-dihydro-2H-1,4-benzodiazepin-2-one (Iss, prepared in Example 35), 2.85 g (0.032 mole) of 2-((2-methoxyethyl)methylamino) ethanol, 20 mL of tetrahydrofuran and 4.8 g (0.032 mole) of sodium iodide was heated in an oil bath at 83° C. under an argon atmosphere for 20 hours. The mixture was cooled and then partitioned between ethyl acetate and 0.6 M sodium bicarbonate solution. The ethyl acetate layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was chromatographed on silica gel, eluting with acetonitrile-methanol (80:20) to give 0.233 g of 5-(2-chlorophenyl)-7-cyano-1,3-dihydro-8-(2-((2-methoxyethyl)methylamino)-ethoxy)-2H-1,4-benzodiazepin-2-one (Iv).
