Procedure

To a solution of EXAMPLE 168B (7.7 g) in tetrahydrofuran (20 mL) at 0° C. was added carbonyldiimidazole (14.9 g). The resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was cooled to 0° C. and ammonium hydroxide (3 mL) was added. The mixture was stirred at room temperature for 2 hours and concentrated. The residue was dissolved in ethyl acetate, washed with brine and concentrated to provide the title compound.
