Reaction Steps

A solution of (3RS,4RS)-1-(tert-butyldimethylsilyl)-4-(isobutoxy)-3-(triphenylmethylamino)azetidin-2-one (160 mg, 0.3 mmol) in tetrahydrofuran (4 mL) was cooled in an ice bath and treated with acetic acid (25 mg, 0.4 mmol) followed by dropwise addition of 1M tetrabutylammonium fluoride (0.6 mL, 0.6 mmol). The mixture was stirred for 20 min and passed through silica gel (10 g) eluted with ethyl acetate. The eluate was concentrated and the residue was chromatographed on silica gel eluted with 20% ethyl acetate:hexane to give the title compound. MS(ES) m/e 423 [M+Na]+.
