Reaction Steps

To (−)-7-amino-5-benzyl-7-methyl-5-azaspiro[2.4]heptane D-mandelate (22.43 g, optical purity: 98% e.e.), 10% Aqueous sodium hydroxide and toluene were added, and the mixture was stirred at room temperature. Thereafter, the toluene layer was separated, washed with saturated brine, and dried with sodium sulfate. The desiccant was removed through filtration, and the filtrate was concentrated under reduced pressure, to thereby yield the title product as pale yellow oil (16.13 g, optical purity: 98% e.e.).
