To a solution of 3.42 g (19.2 mmol) of the compound of Example 532A in 20 ml toluene, was added 2.42 ml (30 mmol) pyridine. The mixture was cooled to 0° C.; 4.025 gm (20.0 mmol) of bromoacetyl bromide (diluted with 5 ml toluene) was added in a dropwise fashion. The reaction mixture was allowed to stir for 5 hours at 0° C. and then was allowed to warm to room temperature. Saturated potassium carbonate solution was added, and the mixture was stirred vigorously for 2 hours. The mixture was extracted with EtOAc; the organic layer was washed with 1N H3PO4, water, and brine.
