Procedure

To a solution of 1-(benzo[d][1,3]dioxol-5-yl)-N-(2-tert-butyl-1-(2-cyano-ethyl)indolin-5-yl)cyclopropanecarboxamide (50 mg, 0.12 mmol) in anhydrous DMF (2.6 mL) was added NH4Cl (230 mg, 4.3 mmol) and NaN3 (280 mg, 4.3 mmol). The reaction mixture was stirred for 30 min at 110° C. in the microwave, filtrated, and purified by preparative HPLC. The solid residue was dissolved in CDCl3 (3 mL) and briefly (2 to 4 min) exposed to daylight, which initiated a color change (purple). After 2 h of stirring open to the atmosphere at room temperature, the solvent was removed and the residue was purified by preparative HPLC to give N-(1-(2-(2H-tetrazol-5-yl)ethyl)-2-tert-butyl-1H-indol-5-yl)-1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide. MS (ESI) m/e (M+H+) 473.0.
