Procedure
(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-[5-chloro-2-methoxy-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Example 1, Step E (0.700 g, 1.46 mmol) and 2-methyl-3-oxo-cyclohex-1-en-1-yl trifluoromethanesulfonate (0.416 g, 1.61 mmol) were reacted by the procedure described in Example 1, Step F. Purification by flash column chromatography on silica gel, eluting with 50% ethyl acetate in hexane followed by precipitation from diethyl ether with pentane afforded the title compound (0.270 g) as an amorphous yellow solid.
