Reaction Steps

To a solution of compound 287 (14 g, 1 eq.) in EtOH (140 mL) was added 3-bromo-1,1,1-trifluoroacetone (8.8 mL, 1.2 eq.). The mixture was stirred at 90° C. for 16 hrs and concentrated in vacuo. DCM (20 mL) and water (20 mL) were added. Organics were dried over Na2SO4, filtered, concentrated under reduced pressure, and flushed on a silica gel column with 5% MeOH/DCM to yield compound 288 as a beige compound in 12% yield. MS (ESI, EI+): m/z=292 (MH+).
