Under a nitrogen atmosphere, lithium aluminum hydride (195.6 mg, 5.153 mmol) was suspended in anhydrous tetrahydrofuran (40 ml) to which, while stirring at −15° C., was subsequently added dropwise an anhydrous tetrahydrofuran (10 ml) solution of ethyl cis-1-benzyl-4-(1-tert-butoxycarbonylaminocyclopropyl)pyrrolidine-3-carboxylate (1.001 g, 2.577 mmol) over a period of 15 minutes. The reaction suspension was stirred for 3.5 hours in an ice bath, gradually mixed with cold water (5 ml) and then stirred for an additional 15 minutes at room temperature. The reaction suspension was filtered through celite (diethyl ether washing), and the resulting filtrate was concentrated under reduced pressure and dried, to thereby obtain 833.9 mg (93.4%) of the title compound as a colorless oil.
