Participants

Reaction Steps

The title compound was prepared according to the procedure of Example 2 starting from 2,2,2-trichloro-1-{10-[(2,2′,6′-trimethyl-1,1′-biphenyl-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl}ethanone of Example 3 (1.8 g, 3.26 mmole), (5-methyl-3-isoxazolyl)methylamine (0.305 g, 2.7 mmole), dimethylsulfoxide (1.06 g, 13.6 mmole), and triethylamine (0.605 g, 6 mmole) in 20 mL of acetonitrile. The residue was flash chromatographed on silica Merck-60 using a gradient from 0 to 35% of ethyl acetate in dichloromethane, to provide an orange-yellow foam. Recrystallization from ethyl acetate/dichloromethane/hexane gave a white powder (0.334 g), m.p. 233-234° C.
