Reaction Steps

To a mixture of 9-(4-nitrophenyl)-1,9-diazaspiro[5.5]undecane (680 mg), 37% aqueous formaldehyde solution (1 mL), and 1,2-dichloroethane (10 mL) was added sodium triacetoxyborohydride (1.57 g), followed by stirring at room temperature overnight. To the reaction mixture were added water and a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with chloroform twice. The extract was dried over anhydrous sodium sulfate and then the solvent was evaporated under reduced pressure to obtain 1-methyl-9-(4-nitrophenyl)-1,9-diazaspiro[5.5]undecane (0.68 g) as a yellow solid.
