Reaction Steps
The compound of Example 55 (1 eq) was weighed into a flask and to this was added EDCI (3 eq), DMAP (1.2 eq), trifluoromethanesulfonamide (1.2 eq) followed by anhydrous THF (0.04 M) and the reaction mixture was then stirred at 25° C., overnight. Worked up with ethyl acetate/water followed by washing the organic layer with 1N HCl, saturated bicarbonate and brine. Trituration with CH2Cl2/hexane (8:2) afforded the desired product in 84% yield.
