実験手順

The dimethyl acetal of 2-(2-methyl-3-methylthioanilino)acetaldehyde (0.1 mole), sodium carbonate (0.06 mole) dissolved in water (50 ml) and benzene (50 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and cooling means. The mixture is cooled to a temperature of about 0°C and α-chloroacetyl chloride (0.11 mole) is incrementally added with stirring. After the addition is completed stirring is continued and the reaction mixture is permitted to warm to room temperature. After this time the mixture is filtered, washed with dilute hydrochloric acid and stripped of solvent to yield the desired product the dimethyl acetal of 2-(N-α-chloroacetyl-2-methyl-3-methylthioanilino)acetaldehyde.
