Reaction Steps

The acid (1 eq) from step 1 of Example 53A was weighed into a flask and to this was added EDCI (1.35 eq), DMAP (1.1 eq), trifluoromethanesulfonamide (1.05 eq) followed by anhydrous THF (0.026 M) and the reaction mixture was stirred at 25° C., 3 h. Worked up with ethyl acetate/water followed by washing the organic layer with 0.05N HCl, saturated bicarbonate and brine. Chromatographic purification then afforded the desired product in 94% yield.
