Reaction Steps

N,N-Diisopropylethylamine (30.0 μL, 0.000172 mol) was added to tert-butyl 2,8-diazaspiro[4.5]decane-2-carboxylate hydrochloride (18.5 mg, 0.0000668 mol) in acetonitrile (1.0 mL, 0.019 mol), followed by methanesulfonyl chloride (10.0 μL, 0.000129 mol). After stirring for 1 h the solvent was evaporated, and the residue was dried under high vacuum and was used in the next step without further purification.
