Publication number: 20060035913Abstract: The present invention provides a process for preparing 2-amino-4-chloro-6-alkoxypyrimidines by reacting the 2-amino-4,6-dichloropyrimidine with an alkali metal alkoxide or a mixture of alkali metal hydroxides and an alcohol, in which the reaction is effected in a polar aprotic solvent (or solvent mixture), the solvent is subsequently distilled off to an extent of >30% and the product is precipitated by adding water during or after the distillation. This process, in which the polar aprotic solvent used may in particular be acetone and which can be performed at temperatures between 5 and 60° C., allows 2-amino-4-chloro-6-alkoxypyrimidines and in particular 2-amino-4-chloro-6-methoxypyrimidine to be prepared in high yields and at simultaneously very marked purity in a particularly economically viable and environmentally benign manner.Type: ApplicationFiled: October 24, 2003Publication date: February 16, 2006Inventors: Sylvia Huber, Thomas Guthner, Wolfgang Moser, Doris Krammer
