Reaction Steps

In analogy to the experimental procedure of example 6b) 6-(3-phenyl-propylcarbamoyl)-1,6-diaza-spiro[3.3]heptane-1-carboxylic acid tert-butyl ester instead of tert-butyl 1-(2,4-dichlorobenzylcarbamoyl)-1,6-diazaspiro[3.3]heptane-6-carboxylate was converted using 4-chlorobenzene-1-sulfonyl chloride into the title compound which was obtained as a colorless sticky solid (25 mg, 17%). MS m/e: 434 (M+H)+.
