YieldReaction ConditionsOperation in experiment
With oxalyl dichloride; N,N-dimethyl-formamide; In dichloromethane; at 0℃; for 0.25h; In a 10 mL flask, the <strong>[5683-31-8]3-(trimethylsilyl)propiolic acid</strong> (3.24 mmol, 0.460 g) was dissolved in dry DCM (1 mL) under argon atmosphere. Oxalyl chloride (3.24 mmol, 0.27 mL) and DMF (0.03 mL) were successively added to the reaction mixture at 0C. After 15 minutes of stirring, the apparition of bubbles stopped. Oxalyl chloride and DCM were evaporated under vacuum. (0115) To a solution of this resulting 100 3-(trimethylsilyl)propynoyl chloride in dry 8 DCM (1 mL) were added dropwise at 0C 33 4-amino-N-(2,5-dimethoxyphenyl) benzenesulfonamide (1.62 mmol, 0.500 g) dissolved in 11 mL of dry DCM and 49 Et3N (0.23 mL, 1.62 mmol). After stirring overnight, the reaction mixture was quenched with a saturated solution of 13 NaCl. The aqueous layer was extracted three times with DCM. The combined organic layers were dried over Na2SO4. After removal under vacuum of the solvent, the crude was purified by chromatography over silica gel (DCM/EP: 60/40 to 100/0) affording the expected 96 compound (28) as a white solid (0.45 g, 1.04 mmol) with 64% yield. (Rf: 0.29 (DCM); mp: 84C).

With oxalyl dichloride; In dichloromethane; N,N-dimethyl-formamide; at 0℃; for 0.25h;Inert atmosphere; In a 10 mL flask, the <strong>[5683-31-8]3-(trimethylsilyl)propiolic acid</strong> (3.24 mmol, 0.460 g) was dissolved in dry DCM (1 mL) underargon atmosphere. Oxalyl chloride (3.24 mmol, 0.27 mL) and DMF (0.03 mL) were successively added to the reactionmixture at 0C. After 15 minutes of stirring, the apparition of bubbles stopped. Oxalyl chloride and DCM were evaporatedunder vacuum.
With oxalyl dichloride; In N,N-dimethyl-formamide; at 0 - 20℃; for 0.5h; [1435] 3-(trimethylsilyl)propioloyl chloride : To a stirred solution of <strong>[5683-31-8]3-(trimethylsilyl)propiolic acid</strong> (0.080 g, 0.562 mmol, 1 eq) in DMF (0.002 mL, 0.022 mmol, 0.04 eq) was added oxalyl chloride (0.053 mL, 0618 mmol, 1.1 eq) at 0C. The mixture was allowed to warm room temperature and stirred 30 minutes. Then, the reaction mixture was concentrated under reduced pressure to obtain 3-(trimethylsilyl)propioloyl chloride. The crude was taken as such to next step.
