Reaction Steps

In analogy to the experimental procedure of example 6b) 6-(Adamantan-1-ylcarbamoyl)-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 an off-white sticky solid (29 mg, 35%). MS m/e: 450 (M+H)+.
