YieldReaction ConditionsOperation in experiment
24% at 70℃; for 5 h; Step 1 ethyl 5-amino-l,3,4-thiadiazole-2-carboxylate To a solution of hydrazinecarbothioamide (10 g, 54.8 mmol) in POCI3 (25 mL) was added ethyl 2-chloro-2-oxacetate (6.1 mL, 54.8 mmol). The reaction was heated to 70°C and stirred for 5 h. POCI3 was completely removed from the reaction mixture under vacuum. The residue was diluted with ice cold water (150 mL) and basified to pH 8 with saturated sodium bicarbonate solution and then extracted with ethyl acetate (200 mL). The organic layer was separated and dried over a2S04, and the solvent was evaporated to obtain crude product. The crude product was purified by flash chromatography (silica gel 100-200?, 2percent methanol and dichloromethane) to afford ethyl 5-amino-l,3,4-thiadiazole-2-carboxylate as a yellow solid (3.1 g, 24percent yield). ? NMR (400 MHz, DMSO-d6): ? 7.94 (s, 2H), 4.29 (q, 2H), 1.27 (t, 3H); LC- MS m/z calcd for [M+H]+ 174.03, found 174.1.

YieldReaction ConditionsOperation in experiment
51% With triethylamine In dichloromethane Example 2 Ii; Compound 4 was prepared according to the Ref: J. Hetero. Chem. 1995, 32, 1693-1702. Then, it was reduced by NaBH4ZLiCl in ethanol solution. Further oxidation by Dess-Martin reagent gave the desired aldehyde 6 in 25 percent overall two-step yield.
