Acetyl chloride → HCID 60207425, compound

Participants

Reaction Steps

To a solution of 5-((3,5-dichloropyridin-4-yl)thio)-4-nitro-N-(pyrrolidin-3-yl)thiophene-2-carboxamide (0.15 g, 0.36 mmol) and acetyl chloride (41.0 mg, 0.54 mmol) in tetrahydrofuran (5.0 mL), was added triethylamine (54.2 mg, 0.54 mmol). The resulting reaction mixture was stirred at ambient temperature for 4 hours. After this time, the reaction mixture was quenched with ice water and stirred at room temperature for 20 minutes and the resulting precipitate was collected by filtration, washed with water (10 mL) and dried in vacuo at 40° C. overnight to afford the title product as an solid (80 mg, 48% yield). 1H NMR (400 MHz, d6-DMSO) δ: 8.98 (2H, m), 8.91 (1H, d), 8.51(1H, m), 3.68 (1H, m), 3.50 (2H, m), 3.23 (2H, m), 2.09 (1H, m), 1.94 (3H, m). MS m/z: 461.17, 363.17 [M+H]+.
