To a solution of 75 (0.85 g, 0.023 mol) and K2CO3 (0.45 g, 0.003 mol) in DMF (5 mL) was added (2-chloro-ethyl)-diethyl-amine (0.37 g, 0.025 mol). The reaction mixture was stirred at RT for 10 hours, poured into water. The precipitate formed was filtered off, washed with water and purified by column chromatography on silica gel using EtOAc/hexane 1:4 as eluent to yield 76 (0.14 g, 15%). M. Wt. 455. LCMS [M+H]+=456.
