Background
The invention relates to a process for preparing arylamides
of heteroaromatic acids by reacting heteroaromatic halogen
compounds with aromatic amines and carbon monoxide in the
presence of a base and a catalyst. According to appellants, they
have found that unexpected advantages are achieved in the claimed
