Reaction Steps

To a suspension of 2-(1,3-dithietan-2-ylidene)-1,2-diphenylethanone (1.88 g, 6.61 mmol) in ethanol (50 mL) was added hydrazine hydrate (0.496 g, 9.92 mmol). The reaction was refluxed for 16 h, cooled to room temperature and concentrated. The residue was neutralized with HCl (1.0 M) to pH 6-7 and extracted with EtOAc/H2O. The organic extract was dried over MgSO4 and concentrated to give the title compound (1.5 g). LCMS m/z=253.4 [M+H]+, 1H NMR (400 MHz, CDCl3) δ ppm 4.01-4.19 (m, 1H), 6.92-7.58 (m, 10H).
