Procedure

(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-[2-chloro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Example 10, Step B (0.350 g, 0.780 mmol) and 2-methyl-3-oxo-cyclohex-1-en-1-yl trifluoromethanesulfonate (0.222 g, 0.858 mmol) were reacted by the procedure described in Example 1, Step F. The crude product was purified by flash column chromatography on silica gel, eluting with 50% ethyl acetate in hexane to afford an orange oil. The oil was dissolved in diethyl ether and precipitated with petroleum ether to afford orange solid (0.180 g).
