Abstract
WITH the view of further pharmacological work by one of us (K. V.-B.), it was decided to synthesize certain esters of chromone-2-carboxylic acid, not previously described1–4. The following compounds were obtained : dimethylaminoethyl-chromone-2-carboxylate hydrochloride (Ia), the methiodide of the base (Ib); tropyl-chromone-2-carboxylate (IIa), its hydrochloride (IIb), methobromide (IIc) and methiodide (IId):
