実験手順

A solution of the product of Example 1G (1.55 g, 2.45 mmol) in dichloromethane (12.5 mL) was treated with trifluoroacetic acid (12.5 mL), stirred at 25° C. for 1 hour and concentrated. The concentrate was partitioned between ethyl acetate and saturated NaHCO3 solution. The organic phase extract was washed with brine, dried over MgSO4, filtered and concentrated to give the title compound (1.4 g) which was used without further purification.
