Procedure

A mixture of 6-benzyl-1-oxa-6-azaspiro[2.5]octane (2 g) and 2-methylprop-2-en-1-amine HCl (2 g) and Hunig's Base (3.44 mL) in ethanol (30 mL) was heated at 70° C. for 18 hours. The mixture was cooled to room temperature and the solvent evaporated under reduced pressure. The residue was partitioned between DCM and brine, the aqueous layer was re-extracted with fresh DCM and the combined organics dried over sodium sulphate, filtered and the solvent evaporated under reduced pressure to afford the subtitled compound. Yield 2.70 g.
