Reaction Steps
The general procedure A was followed using 2-methyl-1H-indole (65.6 mg, 0.5 mmol.) and B2pin2 (126.9 mg, 0.5 mmol, 1.0 eq.) as starting material. The resulting mixture was allowed to stir 16 hours at 50 oC. 5y was obtained as white solid (82.3 mg, 64 %) after purification by silica gel flash chromatography (EtOAc/PE=1:40 v/v). m.p.: 73-75 oC.
