Acetyl chloride → HCID 58423313, compound

Participants

Reaction Steps

To a mixture of (5Z)-5-(2-piperazin-1-ylbenzylidene)-1,3-thiazolidine-2,4-dione (Example 115) and acetyl chloride (36.1 mg, 0.46 mmol) was added triethylamine (93 mg, 0.92 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight and was then treated with sat'd aqueous NaHCO3 (˜25 mL). This mixture was allowed to stir at room temperature for 10 min, and was then extracted with DCM (3×25 mL). The combined organic extract was dried over anhydrous Na2SO4, filtered through a bed of Celite, and the filtrate was conc. in vacuo to afford the product which was purified via reverse phase HPLC (acetonitrile:water: 0.1% TFA=5% to 70%) to afford the title compound as a pale yellow solid (40.0 mg, 35.4%). 1H NMR (300 MHz, DMSO-D6) δ ppm 12.58 (brs, 1 H) 7.94 (s, 1 H) 7.47 (d, 2 H) 7.30-7.07 (m, 2 H) 3.60 (brs, 4 H) 2.90 (brs, 2 H) 2.85 (brs, 2 H) 2.04 (s, 3 H); m/z 331.
