Procedure

To a mixture of 3-aminopyridine (11 g.) and triethylamine (13.0 g.) in dry ethyl acetate (300 ml.) was added a solution of bromoacetyl bromide (26.0 g.) in dry ethyl acetate (26 ml.) over a period of 30 minutes with stirring at 0° to 5° C. and stirring was continued for an additional 2 hours at the same temperature. To the reaction mixture was added a chilled aqueous solution of sodium bicarbonate. After shaking well, the ethyl acetate layer was separated, washed successively with water, an aqueous solution of sodium bicarbonate and water, dried and then concentrated. There was obtained concentrate (200 ml.) containing the title compound. Thus obtained concentrate was used directly in the next step reaction without further purification.
