Participants

Reaction Steps

1-(Methoxycarbonylmethyl)-spiro[indoline-3,4′-piperidin]-2-one (0.013 g, 0.049 mmol) was dissolved in dry THF (1.0 mL) and dry 1,2-dichloroethane (0.3 mL). Octahydro-naphthalen-2-one (0.008 g, 0.054 mmol), glacial acetic acid (0.003 g, 0.049 mmol), MP-cyanoborohydride (Polymer support from Argonaut) (0.043 g, 0.099 mmol) were added and the reaction mixture was stirred at room temperature for 18 hrs. The mixture was then filtered, the resin washed with dichloromethane and the solvent evaporated in vacuo to yield the crude compound. The crude compound was purified via flash chromatography (5% methanol/dichloromethane) to yield the title compound as a foam.
