Procedure

Compound 79 (274 mg, 0.72 mmol) was dissolved in methanol (7 mL), and 10% palladium-carbon (274 mg) was added thereto, followed by stirring in an atmosphere of hydrogen at 50° C. for 24 hours. The reaction mixture was filtered through Celite, and the resulting filtrate was concentrated to afford a free form of the entitled Compound. The resulting free form was dissolved in ethanol (5 mL), fumaric acid (83.0 mg, 0.51 mmol) was added thereto, and the precipitated solid was collected by filtration to afford the entitled Compound 80 (40.1 mg, 14%).
