Reaction Steps

A solution of 8.1 g (0.039 mol) of this 1-(2-methoxyphenyl)imidazoline-2-thione in 88 ml of dimethylformamide is added dropwise, under nitrogen at 0° C., to a suspension of 1.19 g (0.047 mol) of sodium hydride (95%) in 88 ml of anhydrous dimethylformamide. The reaction mixture is stirred for ¾ h at 0° C. 2.7 ml (0.043 mol) of methyl iodide previously diluted in 24 ml of dimethylformamide are added and the mixture is stirred for 1 hour at 0° C. The reaction mixture is poured over ice, extracted three times with ethyl acetate and washed twice with water and then with brine. The product is dried over magnesium sulphate, filtered and concentrated. 8.6 g of oil are obtained.
