Procedure

To a mixture of EXAMPLE 144B (8.3 g) was added water (75 mL) and H2SO4 (25 mL). The mixture was stirred at 0° C. while NaNO2 (3.13 g) in water (30 mL) was added. After stirring for 1 hour, the mixture was added to CuBr (5.45 g) in 48% HBr (200 mL). This mixture was stirred at 60° C. for 3 hours, cooled to room temperature, and partitioned between water and ethyl acetate. The organic layer was washed with aqueous Na2CO3 and dried (Na2SO4), filtered and concentrated.
