Procedure

1-(10-Aza-tricyclo[6.3.1.02,7]dodeca-2(7),3,5-trien-10-yl)-2,2,2-trifluoro-ethanone (530 mg, 2.1 mmol) was added to chlorosulfonic acid (2 mL, 30 mmol) and stirred for 5 minutes. The mixture was quenched with ice, extracted with ethyl acetate, dried (Na2SO4), filtered and concentrated to provide an oil (640 mg, 87%). (TLC 30% ethyl acetate/hexanes Rf 0.15).
