Reaction Steps

Dansyl chloride (37.5 mg, 0.13 mmol) dissolved in dry CH2Cl2 (0.5 mL) was added to the crude 1-[4-(2-dimethylamino-ethyldisulfanyl)-phenyl]-2,2,2-trifluoro-ethanol obtained above. To this solution was added dropwise a solution of DABCO (157 mg, 1.4 mmol) dissolved in dry CH2Cl2 (0.25 mL). After 4 hours at room temperature, the reaction mixture was poured into H2O (30 mL) and extracted using ethyl acetate (3×30 mL). The combined organic phases were washed with H2O (3×30 mL), followed by brine (1×30 mL) and then dried over Na2SO4. The organic phase was collected by filtration and concentrated by rotary evaporation. The crude product thus formed was purified by using flash chromatography on silica gel using 0-2% CH2Cl2/MeOH to yield Compound 2 a yellow oil (8 mg). 1H NMR (400 MHz, CD3OD): δ 8.45 (m, 1H), 8.13 (m, 2H), 7.57 (m, 1H), 7.43 (m, 1H), 7.27 (m, 1H), 7.06 (m, 2H), 6.98 (d, J=8.47, 2H), 5.88 (q, J=6.5 Hz, 1H), 2.8 (s, 6H), 2.78 (m, 2H), 2.57 (m, 2H), 2.21 (s, 6H); 19F NMR (376 MHz, CH3OD): δ −78.1 (d, J=6.5 Hz).
