Reaction Steps

0.207 g of benzyl 4-[4-(1-benzothiazol-2-ylazetidin-3-yloxy)phenyl]-3-[4-(3-methoxypropyl)-3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethoxy]piperidinecarboxylate is dissolved in 8 ml of dioxane. 8 ml each of methanol and 40% KOH are added and the reaction mixture is stirred in a sealed flask at 100° C. over 5 hours. The reaction mixture is subsequently cooled to room temperature, diluted with 40 ml of water and extracted with ethyl acetate (3×40 ml). The combined organic phases are washed with 40 ml of water, dried over sodium sulphate, filtered and concentrated by evaporation. The title compound is obtained from the residue by means of flash chromatography (SiO2 60F).
