Reaction Conditions

Reaction Steps

A mixture of 6 (0.30 g, 1.4 mmol), K2CO3 (0.48 g, 3.5 mmol) and BuBr (0.20 g, 1.4 mmol) was combined in DMF (10 mL) and heated overnight at 60° C. The solvent was evaporated in vacuo and the residue was dissolved in EtOAc, washed with water and then brine and dried over Na2SO4. After filtration, the filtrate was evaporated in vacuo to give the crude product which was purified by chromatography (CH2Cl2/(9:1) MeOH/NH4OH) to give the title compound (0.25 g, 80%) as a colorless syrup. MH+=224. 1H NMR (DMSO-d6) 6.2 (t, 1H, J=57 Hz), 5.13 (d, 1H, ex), 4.91 (d, 1H, ex), 3.3 (m, 1H), 3.1 (m, 1H), 2.9 (m, 2H), 2.3 (m, 2H), 1.95 (m, 2H), 1.75 (t, 1H), 1.2-1.5 (2m, 4H), 0.9 (t, 3H).
