Procedure

To a solution of 6-chloro-1-methyl-1H-pyrrolo[2,3-b]pyridine (1.02 g, 6.12 mmol)) in THF (60 mL) at −78° C. was added 1.7 M t-BuLi in pentane (9.00 mL, 15.31 mmol) and the mixture was stirred at −78° C. for 2 h. Trimethyl borate (1.026 mL, 9.18 mmol) was added at −78° C. and the mixture was allowed to warm to room temperature, and stirred at room temperature overnight. Water (2 mL) was added and the mixture was concentrated in vacuo. The solid was subjected to high vacuum overnight to afford 2.1 g of 6-chloro-N-methyl-7-aza indole-2-boronic acid. ESI-MS: m/z 211.1 (M+H)+
