Participants

Reaction Steps

To an ice bath cooled solution of D6 (340 mg, 0.82 mmol) in acetone (10 mL) was added triethylamine (0.29 mL, 2.1 mmol) followed by trifluoromethanesulfonyl chloride (0.13 mL, 1.2 mmol). The mixture was stirred at room temperature for 2 hours. The solvent was removed and the residue partitioned between dichloromethane and saturated sodium bicarbonate. The organic layer was removed, dried (MgSO4) and evaporated to yield the title compound D7 as a solid (270 mg). MH+ 468. 1H NMR δ (CDCl3) 2.42 (3H, s), 2.55-2.70 (4H, m), 2.95-3.15 (4H, m), 7.09 (1H, s), 7.15-7.24 (2H, t), 7.93-8.04 (3H, m).
