Procedure
3-(4-Methoxyphenyl)-1,4-dimethyl-1-azaspiro[4.5]dec-3-ene-2-one (881 mg, 3.09 mmol) and N-bromosuccinimide (1.2 eq.) were stirred in 40 mL CCl4 with a catalytic amount of benzoyl peroxide for 3 h at 85° C. After cooling to room temperature the mixture was diluted with CH2Cl2, washed with water, dried (Na2SO4) and evaporated. The 4-bromomethyl-3-(4-methoxyphenyl)-1-methyl-1-azaspiro[4.5]dec-3-ene-2-one thus obtained was dissolved in ethanol (100 mL), CH2Cl2 (20 mL), and ethylamine (70% solution in water, 2 mL), the mixture was stirred overnight at room temperature and concentrated. The residue was dissolved in CH2Cl2, washed with water and extracted with 0.5 M HCl.
