Versuchsvorschrift

In analogy to the experimental procedure of example 8) 1,6-diaza-spiro[3.3]heptane-1-carboxylic acid tert-butyl ester instead of 1-benzyl-1,6-diaza-spiro[3.3]heptane was converted using 1-isocyanato-adamantane instead of (3-isocyanato-propyl)-benzene into the title compound which was used directly in the next step without further purification.
