Procedure
Dimethyl-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-amine 110 (1.25 g, 3.77 mmol) was added to toluene (20.0 mL) under an atmosphere of nitrogen at room temperature. Isopropyl chloroformate in toluene (1.0 M, 4.0 mL) was added. The reaction mixture was stirred at room temperature for 3 hours to provide a solution of 3-chloromethyl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine.
