Procedure

100 mg of compound 60 were dissolved in 2 ml of DCM/DMF 1:1 solution, containing 2 eq of DIEA. Under stirring and at 0° C., 6 eq of acetylchloride were added portionwise during 30 minutes. The solution was stirred overnight at rt, then water was added and a precipitate formed. The precipitate was separated and the title compound was obtained after preparative HPLC purification.
