Abstract
The invention comprises 12,13,14-trimethoxy-3a - acetamido - 4,5 - 6,7 - dibenzo - cycloheptadiene-10-carboxylic acid: <FORM:0839164/IV (b)/1> and esters thereof, especially esters with alcohols containing 8 carbon atoms or less; and the preparation thereof by heating the sulphone of isothiocolchicine with an alkali metal alcoholate in alcohol and, if desired, esterification of the product with diazomethane or a homologue thereof.
