Reaction Steps

A 5 N aqueous HCl solution (2.0 ml, 10 mmol) was added to a solution of a mixture of 4-[1-(1,4-dioxa-8-aza-spiro[4.5]decane-8-sulfonyl)-cyclopropylmethyl]-3,5-dimethyl-phenyl}-methyl-carbamic acid tert-butyl ester (54.7 mg, 0.111 mmol) and {4-[1-(1,4-dioxa-8-aza-spiro[4.5]decane-8-sulfonyl)-cyclopropylmethyl]-3,5-dimethyl-phenyl}-methyl-amine (23.1 mg, 0.0585 mmol) in EtOH (2.0 mL), and the mixture was stirred at 80° C. for two hours. The reaction mixture was neutralized by adding a 5 N aqueous NaOH solution (1.9 ml) and then extracted with ethyl acetate. The organic layer was dried over MgSO4 and concentrated under reduced pressure to give 1-[1-(2,6-dimethyl-4-methylamino-benzyl)-cyclopropanesulfonyl]-4-piperidinone (58.8 mg, 99%).
