Procedure

(s)-3-((s)-2-tert-Butoxycarbonylamino-4-methylvalerylamino)-1-furfurylthio-2-heptanone (8.47 g) obtained in Example 1 was dissolved in ethyl acetate (25 ml), and 4N hydrogen chloride-containing ethyl acetate solution (25 ml) was added to the solution. After the mixture was stirred at room temperature for 50 minutes, hexane (50 ml) was added to the mixture. Then, the resultant crystals were filtered, and washed with hexane to give the titled product (4.31 g).
