Procedure

4′-[Bis-(4-methoxyphenyl)-methylsulfanyl]-6-methylbiphenyl-3-ylamine (˜10 mmol) and 1-benzo[1,3]dioxol-5-yl-cyclopropanecarboxylic acid (2.28 g, 11 mmol) were dissolved in chloroform (25 mL) followed by addition of TCPH (4.1 g, 12 mmol) and DIEA (5.0 mL, 30 mmol). The reaction mixture was heated at 65° C. for 48 h. The volatiles were removed under reduced pressure. The residue was distributed between water (200 mL) and ethyl acetate (150 mL). The organic layer was washed with 5% NaHCO3 (2×150 mL), water (1×150 mL), brine (1×150 mL) and dried over MgSO4. Evaporation of the solvent yielded crude 1-benzo[1,3]dioxol-5-yl-cyclopropanecarboxylic acid 4′-[bis-(4-methoxyphenyl)-methylsulfanyl]-6-methylbiphenyl-3-ylamide as a pale oil, which was used without further purification. ESI-MS m/z calc. 629.0, found 630.0 (M+1) (HPLC purity ˜85-90%, UV254 nm).
