Reaction Steps

tert-Butyl 1-methyl-1-hydroxyspiro[indane-3,4′-piperidine]-1′-carboxylate (0.140 g, 0.441 mmol) obtained in step 1 was dissolved in methylene chloride (2 mL), toluenesulfonic acid monohydrate (0.008 g, 0.044 mmol) was added, and the mixture was stirred at room temperature for 3 hr. Saturated aqueous ammonium chloride solution was added dropwise to the reaction mixture, and the mixture was extracted several times with ethyl acetate. The combined organic layers were dried over magnesium sulfate and concentrated under reduced pressure to give the title compound (0.108 g, 81%).
