  • ethyl 5-((3,5-dichloropyridin-4-yl)thio)-1,3,4-thiadiazole-2-carboxylate [ No CAS ]
YieldReaction ConditionsOperation in experiment
69% With potassium carbonate; In N,N-dimethyl-formamide; at 65℃; for 2.0h;Inert atmosphere; A mixture of <strong>[64837-49-6]ethyl 5-chloro-1 ,3,4-thiadiazole-2-carboxylate</strong> (2.31 g, 12.00 mmol) and 3,5-dichloropyridine-4-thiol (2.484 g, 13.80 mmol) in DMF (48 mL) was treated with K2CO3 (3.65 g, 26.4 mmol). The reaction mixture was stirred at 65QC for 2 h. The reaction was cooled to room temperature, quenched with H2O, and extracted with EA. The combined organic extracts were washed with H2O and brine, dried over Na2SO4. The solvent was removed and the residue was purified by flash column (Hex:EA = 5:1 ) to afford 2.776 g (69%) of ethyl 5-((3,5-dichloropyridin-4-yl)thio)-1 ,3,4-thiadiazole-2- carboxylate as a yellow solid. 0.25 (Hex:EA = 4:1 ); HRMS (ESI) (m/z) [MH]+calcd for C10H8CI2N3O2S2, 335.9435, found 335.9205.

YieldReaction ConditionsOperation in experiment
30% With potassium carbonate; In N,N-dimethyl-formamide; at 70℃; for 4h;Inert atmosphere; A mixture of <strong>[72605-86-8]methyl 2-chlorothiazole-5-carboxylate</strong> (2.1 3 g, 1 2.0 mmol) and 3,5- dichloropyridine-4-thiol (2.38 g, 14.4 mmol) in DMF (48 imL) was treated with K2CO3 (3.65 g, 26.4 mmol). The reaction mixture was stirred at 70QC for 4 h. The reaction was cooled to room temperature, quenched with H2O, and extracted with EA. The combined organic extracts were washed with H2O and brine, dried over Na2SO4. The solvent was removed and the residue was purified by flash column (Hex:EA = 1 0:1 ) to afford 1 .23 g (30%) of methyl 2-((3,5-dichloropyridin-4-yl)thio)thiazole-5-carboxylate as a yellow solid.0.50 (Hex:EA = 4:1 ); HRMS (ESI) (m/z) [MH]+calcd for C10H7CI2N2O2S2, 320.9326, found 320.9433.
