Procedure:
Anhydrous CrO3 (2.274 g, 22.74 mmol) is added to a solution of anhydrous pyridine (3.597 g, 45.48 mmol) in anhydrous CH2Cl2 (60 ml). After stirring at room temperature (25° C.) for 15 mins, the reaction mixture is treated all at once with a solution of N-(t-butyldimethylsilyl)-4-(3-benzyloxycarbonyl-2-hydroxypropyl)-azetidin-2-one (1.432 g, 3.79 mmol) in anhydrous CH2Cl2 (25 ml). The resulting mixture is stirred at 25° C. for 5 mins. The CH2Cl2 layer is decanted from the dark, gummy residue which is triturated with more CH2Cl2. The combined CH2Cl2 phase is evaporated i.v. The residue is triturated with diethylether (Et2O) (100 ml) in several portions and the Et2O extracts are filtered to remove chromium salts. The ethereal filtrate is washed with 5% NaHCO3, 1N HCl, 5% NaHCO3 and brine, dried with MgSO4, filtered, and evaporated i.v. to yield N-(t-butyldimethylsilyl)-4-(3-benzyloxycarbonyl-2-oxopropyl)-azetidin-2-one (1.042 g) as a pale yellow oil: ir (neat) 5.72 (3 poorly resolved peaks), 7.59 7.98, 8.42, and 11.93 cm-1 ; nmr (CDCl3)δ 0.18 (s, 3), 0.22 (s, 3), 0.97 (s, 9), 2.53 (dd, 1), 2.63 (dd, 1), 3.13 (dd, 1), 3.28 (dd, 1), 3.47 (s,2), 3.88 (m, 1), 5.17 (s, 2), and 7.33 (s, 5); mass spectrum m/e 360, 318, and 2.76.

TLC showed the starting material was not consumed. A further portion of Cs2CO3 (300 mg, 0.92 mmol, 1.5 eq) was added and the reaction stirred for 1 h, then a further portion of isopropyl bromoacetate (134 mg, 0.74 mmol, 1.2 eq) was added and the reaction stirred for 4 h. The resulting mixture was poured into water and extracted with EtOAc. The organic extract was washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether:EtOAc, 50:1 to 20:1) to give the title compound as a colorless oil (225 mg, 80%).

Procedure:
To a solution of tert-butyl 4-oxopiperidine-1-carboxylate (7.5 g, 37.8 mmol) in pyrrolidine (4.5 mL, 54.1 mmol) and anhydrous methanol (10.2 mL) was added 1-(4-fluoro-2-hydroxy-phenyl)ethanone (5.8 g, 37.6 mmol). The reaction mixture was stirred at 80° C. for 2.5 hours. The methanol was removed under reduced pressure and the resulting residue was dissolved in ethyl acetate (150 mL), washed with 1N HCl (1×150 mL) and brine (2×100 mL). The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to yield a yellow oil. The oil was diluted with hexanes (400 mL) and was heated at 60° C. until in solution. Once dissolved, the solution was allowed to cool to 25° C. The crystals were collected via vacuum filtration, rinsing with hexanes to remove tert-butyl 4-oxo-7-pyrrolidin-1-yl-spiro[chromane-2,4′-piperidine]-1′-carboxylate (8.6 g), which was collected as light yellow solid; ESI-MS m/z calc. 386.2. found 387.2 (M+1)+; Retention time: 2.59 minutes (3 min run).
