実験手順

A solution of Example 140D (0.5 g, 2.5 mmol), and aniline (0.23 mL, 2.5 mmol) in THF (25 mL) and 2-propanol (2.5 mL) was stirred at 0° C. for 1 h then at room temperature for 2 days. The THF was evaporated off and the residue was taken into ethyl acetate (75 ml), washed with water (50 ml) and brine (50 ml). The ethyl acetate was evaporated off and the residue was purified by flash column chromatography on silica gel, eluting with 1:1 ethyl acetate/hexane. Recovered 0.15 g of product (23%). MS (ESI) m/z 390 (M+H)+.
