The solution was cooled to 00C and after 10 minutes HATU (620 mg, 1.63 mmol) was added. After approximately 2 hours at RT, LC-MS showed product and no starting material and the solvent was removed by rotary evaporation. The crude product was dissolved in 40 rnL of EtOAc and washed with 25 rnL of sat. NaHCCh (aq). The organic phase was dried with Na2SO4, filtered and evaporated to dryness. The crude product was purified on a 25 g silica column on a Biotage Flashmaster eluted with a gradient of heptane:ethyl acetate 1 :1, which gave the title compound as a white solid (488 mg, 92percent) yield.
