The compound prepared in Example 126 (1.00 g) was suspended in tetrahydrofuran (20 mL) and dimethylamine (2 M) (7.66 mL) added and the reaction mixture stirred at room temperature for 3 hours. The reaction mixture was partitioned between saturated aqueous sodium bicarbonate and ethyl acetate. The organics were washed with brine, dried, magnesium sulfate and concentrated under reduced pressure to afford the crude material, which was purified by flash column chromatography to afford the title compound (0.65 g) having the following physical data.
