Procedure

A solution of 0.75 g (4.02 mmol) of methyl 5-amino-6-chloronicotinate and 0.43 g=0.35 ml (4.5 mmol) of methoxyacetylchloride in 20 ml of chlorobenzene was stirred for one hour at 110° C. After the solvent had been removed in vacuo, the crude product obtained was purified by flash chromatography (silica gel; methylene chloride/ethanol=100:1), evaporated down again in vacuo and then digested with petroleum ether.
