Procedure

To C7 (0.946 g, 2.14 mmol) in dichloromethane (22 mL) was added benzoyl isothiocyanate (0.273 mL, 2.04 mmol) and the resulting solution was allowed to stir at room temperature for 18 hours. The reaction mixture was concentrated in vacuo, providing the product as an orange oily residue, which was carried forward into the next step without further purification. Yield: 964 mg, 1.59 mmol, 74%. LCMS m/z 607.6 [M+H+], Br isotopic pattern. 1H NMR (400 MHz, CD3OD), characteristic peaks: δ 7.89-7.90 (m, 2H), 7.62-7.66 (m, 2H), 7.50-7.54 (m, 2H), 7.31 (d, J=6.6 Hz, 2H), 7.18-7.25 (m, 2H), 7.06 (dd, J=11.9, 8.8 Hz, 2H), 4.52-4.59 (m, 2H), 3.84-3.90 (m, 3H), 3.55-3.64 (m, 3H), 3.45-4.51 (m, 1H) 1.90-1.99 (m, 3H).
