Reaction Conditions

Reaction Steps

To a 0° C. suspension of NaH (43 mg, 1.81 mmol) in THF (4 mL) was added a solution of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole (400 mg, 1.65 mmol, Aldrich) in THF (4 mL). The reaction mixture was maintained at 0° C. for 15 min, iodoethane (0.200 mL, 2.47 mmol) was added and the reaction was heated at 50° C. for 30 min. The mixture was partitioned between water and EtOAc. The aqueous layer was extracted with EtOAc and the combined organics were washed with brine, dried (Na2SO4), filtered, and concentrated. Chromatography over silica eluting with 1-8% EtOAc/hexanes afforded the title compound as a white solid. LC-MS: calculated for C16H22BNO2 271.16, observed m/e 273.2 (M+H)+ (Rt 2.09 min).
