Reaction Steps

A mixture of 8-(4-chloro-3-methoxyphenyl)-1,4-dioxa-8-azaspiro[4.5]decane (1.67 g, 5.89 mmol, Example 13, step 1) and 1-chloropyrrolidine-2,5-dione (0.786 g, 5.89 mmol) in AcOH (15 mL) was heated at 60° C. overnight. The mixture was cooled and water was added. Upon completion of addition, the mixture was neutralized with 1N NaOH, extracted with EtOAc, dried (Na2SO4), and concentrated to give 8-(2,4-dichloro-5-methoxyphenyl)-1,4-dioxa-8-azaspiro[4.5]decane (1.7 g, 5.34 mmol, 91% yield) as a yellow oil.
