This experiment is performed according to literature method [1,2,3,4]. 3(5)-Methoxycarbonyl-5(3)-pyrazole 1 (3.35 g, 0.024 mol) and triethylamine (6,65 g, 0.048 mol) in ethanol solution were cooled to 5°C under stirring, carbon disulfide (3,65 g, 0.048 mol) was added to the solution. After 1 hour of stirring, solid iodine (2,8 g, 0.022 mol) was added in portions and stirred until the colour disappeared completely. Then a methanolic solution of iodine was added dropwise until a faint colour persists. Excess of iodine was neutralized with Na2S2O3 solution. The product was extracted with diethyl ether, washed thrice with water, dried over Na2SO4, filtered, and diethylether was evaporated at room temperature to give liquid compound 2.
Yield: (90%).
1H-NMR(CDCl3) d (ppm): 2,30 (s, 6H, CH3); 4,86 (s, 6H, CO2CH3); 6,53 (s, 2H, Hpy).
13C-NMR(CDCl3) d (ppm): 166 (CO2), 126 (C3), 52 (O-CH3)
IR (KBr , cm-1) : 3200 (-S-S-); 1720 (C=O); 1240 (C=S), 166 (CO2), 126 (C3), 52 (O-CH3).
MS (m/z): 430 [M]+.
U.V.: lmax = 290 nm (-C=S).
