More Information
Summary:The invention relates to a novel process for the preparation of a chiral piperazine-2- carboxylic acid or of a salt thereof of the formula (I). The chiral piperazine-2-carboxylic acid derivatives of the formula (I) are key intermediates for the preparation of fused heteroaryl dihydro pyrimidines which are useful for the treatment and prophylaxis of hepatitis B virus infections.
