Procedure

A mixture of 3,3-diallyl-1-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one from Step D (1.02 g, 2.96 mmol) and Grubbs second generation catalyst (37 mg, 0.045 mmol) in DCE (60 mL) was heated at reflux for 3.5 h. The mixture was concentrated in vacuo and purified by silica gel chromatography, eluting with a gradient of hexane:EtOAc—100:0 to 75:25, to give the title compound. MS: m/z=317 (M+1).
