Procedure
To a mixture of diethyl cyanomethylphosphonate (145 mg, 0.76 mmol), LiCl (43 mg, 1.01 mmol) and DBU (255 mg, 1.01 mmol) in acetonitrile (15 mL) was added a solution of tert-butyl 1-(2-(4-chlorophenyl)-1-oxobutan-2-yl)-1H-indol-4-ylcarbamate (210 mg, 1.02 mmol), as described in Example 21 Step B, in acetonitrile (3 mL). The mixture was stirred at room temperature for 2 h and the volatile was evaporated. The residue was purified by silica gel chromatography eluting with PE/EA (10/1 to 3/1, v/v) to afford the title compound as a white solid. LC/MS m/z=458.1 [M+Na]+.
