YieldReaction ConditionsOperation in experiment
20% for 20 h; Heating / reflux intermediate 3; 2-Bromo-imidazo[2,1-b][1,3,4]thiadiazole; To a suspension of 2-amino-5-bromo-1 ,3,4-thiadiazoie (1.65 g, 9.15 mmol) in water (27 mL) was added a water solution of chloroacetaldehyde (50percent wt, 1.7 mL). The mixture was stirred at reflux. After 10 hours, a second addition of chloroacetaldehyde (1.5 eq, 1.7 mL) was done and stirring was continued until disappearance of starting material (20 hours). After cooling, the reaction mixture was neutralized with sodium bicarbonate (sat. aq. solution) and extracted with dichloromethane (3 x 30 mL). The combined organic layers were dried over sodium sulphate and the solvent evaporated under vacuum. The crude product was triturated with diethyl ether to yield 2-bromo-imidazo[2,1-b][1 ,3,4]thiadiazole as a white solid. The mother liquor was purified by flash chromatography (Biotage .(TM)., ethyl acetate:hexane, 3:7 to 7:3) to yield another batch of compound (20percent global yield) as a white solid.1H NMR (300 MHz, CDCI3): δ 7.64 (s, 1 H), 7.24 (s, 1 H). MS (ES+) m/z 204 (M+H)+ (MW: 204.05).
14% Reflux Intermediate G; 2-Bromoimidazo[2,1 -b][1 ,3,4]thiadiazoleTo a suspension of 5-bromo-1 ,3,4-thiadiazol-2-amine (60 g, 0.33 mol) in H2O (1.5 L), a solution of chloroacetaldehyde (50percent wt in water, 64.5 mL, 0.50 mol) was added, and the mixture was stirred at reflux temperature for 5h. A second portion of chloroacetaldehyde (20.6 mL, 0.5 eq) was added, and stirring was continued overnight. The starting material had been consumed completely, and the reaction mixture was cooled to RT. The solid was removed by filtration and washed with water. The mother liquor was neutralized with a sat. aq. solution of NaHCO3 and extracted with DCM (2x 1 L). The organic layers were washed with brine (2x 60OmL), dried and evaporated in vacuo. The brown residue obtained was triturated with a mixture of MeOH and MTBE (1 :1 , 7OmL) to afford the desired product as a pale yellow solid. The mother liquors were purified by chromatography (SiO2, DCM) to yield some more product. Combined yield: 9.4 g (14 percent). MS (ESI+): m/z=204 [M+Hf; 1H-NMR(CDCI3): 7.36 (d, 1H); 7.56 (d, 1H).
