Reaction Steps

To a solution of the product of step 3 in DMF (52 mL) at 0° C. was added DIPEA (3.1 mL) and HATU (1.64 g). The mixture was stirred at room temperature for 2 hours until disappearance of the starting material. The reaction mixture was diluted with Et2O and quenched with water and HCl (1N). The mixture was extracted (3×) with ether. The combined organic phases were washed with water then brine, dried over sodium sulfate, filtered and concentrated. Purification by flash chromatography (ISCO, 0 to 100% ethyl acetate in hexanes) afforded the desired product (1.3 g). LRMS (ES+) m/z 640.45 (M+H)+.
