Versuchsvorschrift

To a solution of 9.42 g. (0.1 mole) of 2-aminopyridine in 50 ml. of methylene chloride was added dropwise 4.0 ml. (0.05 mole) of chloroacetyl chloride in 20 ml. of the same solvent, keeping the reaction temperature at -20° to -10° C. for one hour. After stirring at room temperature for 10 hours, 50 ml. of water was added and the organic layer separated. The organic solution was washed with water and a brine solution and was dried over magnesium sulfate. Removal of the solvent in vacuo gave 6.64 g. (78%), m.p. 114°-117° C., of the desired product.
