실험 절차

A mixture of the product from step (iv) (9.51 g) and pentylamine (12 ml) in dioxane (100 ml) was heated under reflux for 48 h. The solvent was evaporated and the residue partitioned between EtOAc/water. The organics were separated, washed with aq NaHCO3 soln, water, dried and evaporated under reduced pressure. The residue was dissolved in MeOH (200 ml) then aq NaOH (2M, 40 ml) added and the mixture heated under reflux for 6 h. The mixture was acidified to pH 7 with aq 2M HCl, the solvent evaporated under reduced pressure and the residue partitioned between DCM/water. The organics were separated, washed with aq NaHCO3 soln, brine, dried and evaporated under reduced pressure. The residue was triturated with ethyl acetate and filtered to afford the subtitle compound, 2.43 g.
