Reaktionsbedingungen

Temperatur100 °C

Reaktionsschritte

17.0 g (0.15 mol) of cysteaminium chloride and 19.8 g (0.3 mol) of potassium hydroxide are boiled for 3 hours on a water separator in 180 ml of toluene. 24.6 g (0.1 mol) of 2-chlorothioxanthone and 180 mol of dimethylpropyl-eneurea are added to the evaporated residue, and the mixture is stirred for 20 hours at 100° C. The reaction mixture is poured into 1 l of 2N hydrochloric acid and the aqueous phase is extracted with ethyl acetate. The aqueous phase is then adjusted to pH 10 and extracted with ethyl acetate. Work-up of the organic phase gives 24.0 g of the analytically pure compound IIIb.
