Following the same procedure as described in 46.5, 1-[3-(4-nitro-phenyl)-azetidin-1-yl]-propan-1-one (480 mg, 2.04 mmol) in EtOH (20 ml) was treated with SnCl2.2H2O (2.25 g, 9.97 mmol) and half of the resulting aniline in CH2Cl2 (15 ml) was then treated with pyridine (140 μl, 1.71 mmol) and 4-isopropylbenzensulfonylchloride (230 μl, 1.28 mmol). Purification of the crude product by flash column chromatography (heptane:ethyl acetate, 1:1) provided the title compound (140 mg, 36% for two steps) as a pale yellow gum.
