This experiment is performed according to literature method [1,2,3,4]. To a solution of bis[(3- methoxycarbonyl-5-methyl pyrazol)-1-yl thiocarbonyl] disulfide 1 (7.3x10^-2mol) in dry diethyl ether was added a solution of LiAlH₄ (2.78 g, 7.3x10^-2mol) in 10 mL of dry ether. The mixture was stirred for 6h at 30 °C and the product was extracted with CHCl₃ dried over Na₂SO₄ and filtred. The solvent was removed under reduced pressure and the product was dried under high vacuum.

Yield: (70%).

¹H-NMR (DMSO) d (ppm): 2,16 (s, 6H, CH3); 4,33 (s, 4H, CH2); 5,86 (s, 2H CH).

¹³C-NMR (CDCl₃) d (ppm): 193 (-C=S), 65 (CH₂-OH).

IR (KBr , cm^-1): 3300 (-S-S-); 1240 (C=S).

MS (m/z): 374 [M]⁺.

U.V.: l_max = 290 nm (-C=S).
