Reaction Steps

(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Example 2, Step B (0.500 g, 1.17 mmol) and 2,6-dimethyl-cyclohex-1-en-1-yl trifluoromethanesulfonate (0.401 g, 1.29 mmol) were reacted in the manner of Example 2, Step C. Purification by flash column chromatography on silica gel, eluting with 30% ethyl acetate in hexane, followed by recrystallization from petroleum ether (−20° C.) afforded the title compound as white crystals, m.p. 133–135° C.
