YieldReaction ConditionsOperation in experiment
With thionyl chloride; In methanol; water; Example 1(a) Preparation of 2,3-dichloro-5-(methoxymethyl)pyridine Under argon and at room temperature, 4.14 g (23 mmol) of sodium methoxide (30 percent strength solution in methanol) was added dropwise within 5 minutes to a solution of 4.11 g (20.9 mmol) of <strong>[54127-31-0]2,3-dichloro-5-(chloromethyl)-pyridine</strong> [prepared from 2,3-dichloro-5-(hydroxymethyl)-pyridine by reaction with thionyl chloride] in 40 ml of methanol. The reaction mixture was subsequently heated to 60 C. for 3 hours. After the reaction had ended, the solvent was distilled off and the residue was admixed with 100 ml of water and extracted with dichloromethane (3*75 ml). The organic phase was dried over magnesium sulfate and evaporated. The yield of the product was 4.06 g (90.4 percent) of a yellow oil, purity (GC) 90.8 percent. For analysis, the product was chromotographed over silica gel using hexane/ethyl acetate (3:1). MS (m/z): 192 (M+); 176; 161; 148; 124; 112.
