Versuchsvorschrift
Following the process described in example 2 (point K), starting from 2-(3-phenylpropyl)-6-chromanecarboxylic acid and 8-amino-4-oxo-2-(5-1H-tetrazolyl)-4H-1-benzopyran, the title compound was prepared as a white solid which decomposes at temperatures higher than 370° C. and which was purified by crystallization in methanol (65% yield).
