Participants

Reaction Steps

To a solution of 4,7-difluoro-2,3-dihydro-1H-inden-1-amine (CAS No. 625471-13-8, 1.19 g, 11.2 mmol) in DCM (50 mL) were added [(tert-Butoxy)carbonyl]{[4-(dimethyliminio)pyridin-1(4H)-yl]sulfonyl}amide (3.70 g, 12.3 mmol) and TEA (4.66 mL, 33.5 mmol) at room temperature. The resulting solution was stirred for 75 hours at room temperature. The reaction mixture was diluted with AcOEt and 1N HCl and the layers were separated. The organic layer was dried over anhydrous Na2SO4 and evaporated in vacuo to afford the title compound (3.82 g, 11.0 mmol).
