Procedure

The compound obtained in Example 193 (4.08 g, 7.34 mmol) was dissolved in methanol (20 mL). To the solution was added a solution of 4N-hydrogen chloride in ethyl acetate (40 mL), and the mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, and to the concentrate was added diethyl ether. The resulting precipitates were collected by fltration, washed with diethyl ether, and dried under reduced pressure to give the titled compound (4.07 g) as white amorphous substance.
