Vorschrift

1 ml of an aqueous solution of 39 mg (0.402 mmol) of sulfamic acid and then 1 ml of an aqueous solution of 37.6 mg (0.416 mmol) of sodium chlorite were added dropwise to a solution of 58.4 mg (0.310 mmol) of 2-(1-phenylcyclopentyl)acetaldehyde [prepared as described in step (v) above] in 1 ml of t-butanol at room temperature, and the resulting mixture was stirred for 1 hour at room temperature, after which it was extracted with methylene chloride. The extract was washed with water and then dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, to give colorless crystals. These were recrystallized from a mixture of ethyl acetate and hexane, to give 57 mg (yield 90%) of the title compound as plate-like crystals.
