Participants

Reaction Steps

A solution of 1-[3,5-bis(trifluoromethyl)phenyl]-N2-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}ethane-1,2-diamine (8.0 mg, 0.014 mmol) and sulfamide (2.0 mg, 0.021 mmol) in pyridine (300 μL) was heated to 120° C. in a sealed tube. After 3 hours, the reaction was cooled to room temperature and diluted with 25 mL of EtOAc. The organic solution was washed with 1 N HCl (2×5 mL) and brine (1×5 mL), dried over Na2SO4, filtered, and concentrated. Purification of the residue by PTLC with 25% EtOAc/hexanes afforded 4-[3,5-bis(trifluoromethyl)phenyl]-2-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}-1,2,5-thiadiazolidine 1,1-dioxide. Rf=0.29 (25% EtOAc/hexanes). LCMS=641.1 (M+1)+. 1H NMR (CDCl3, 500 MHz; atropisomers present) δ 7.58-7.85 (m, 5H), 7.35-6.86 (m, 4H), 4.82-4.94 (m, 2H), 3.54-4.42 (m, 6H), 2.71-2.91 (m, 2H), 1.11-1.26 (m, 6H).
