Procedure

To a stirred solution of E2 in DMF (0.1 M) were added HATU (1.5 eq.) and DIPEA (2.0 eq.) followed after 10 min by methylamine (2.0 M solution in THF, 5 eq.). Reaction mixture was stirred at room temperature for 16 h, then it was diluted with EtOAc, washed with sat. aq. NaHCO3 sol., brine, dried over Na2SO4, filtered and concentrated to give a dark brown residue. The resulting crude was purified by column chromatography (eluent: petroleum ether/EtOAc from 9:1 to 100% EtOAc, then EtOAc/MeOH=95:5) to give the title compound as a colorless oil. MS (ES+) C30H34N4O4: 515 (M+H)+.
