Procedure:
To a solution of potassium t-butoxide (27.5 g) in N,N-dimethylformamide (120 ml) was added dropwise a solution of benzyl alcohol (15.9 ml) in N,N-dimethylformamide (60 ml) over min. The mixture was stirred for 30 min, and a solution of 4-fluoro-3-trifluoromethylbenzoic acid (20.0 g) in N,N-dimethylformamide (90 ml) was added under ice-cooling. The mixture was stirred at room temperature for 1 hr, and further at 50° C. for 1 hr. The reaction mixture was added to ice water, and acidified with 1M hydrochloric acid (300 ml). The precipitated solid was collected by filtration, and washed with water and then hexane to give the object product (28.2 g) as a white powder.

Procedure:
7.76 g of methyl 2-hexyl-3-oxo -5-[(tetrahydro-2H-pyran-2-yl)oxy]hexadecanoate (0.017 mol) were dissolved in 500 ml of THF while gassing with argon, treated with 20 ml of MeOH and cooled to -5° C. 5.3 g of sodium borohydride (0.14 mol) were added portionwise while stirring in such a manner that the temperature did not exceed 0° C. After stirring for 3 hours the excess sodium borohydride is filtered off, the reaction mixture was hydrolyzed (to pH 6) with 2N hydrochloric acid in the cold and the solvent was evaporated off. The residue was extracted with ether and the ethereal phase was dried and evaporated. There were obtained 7.71 g of methyl 2-hexyl-3-hydroxy-5-[(tetrahydro-2 H-pyran-2-yl)oxy]hexadecanoate.

Procedure:
Ethyl 4-iodobenzoate (600 mg, 2.17 mmol) was dissolved in tetrahydrofuran (6.0 mL) and brought to −40° C. Isopropylmagnesium chloride lithium chloride complex solution (1.0 M in tetrahydrofuran, 0.365 mL, 2.17 mmol) was added dropwise and the yellow-red solution was stirred at −40° C. for 40 min. CuI (124 mg, 0.65 mmol) was added in one portion and the mixture was then stirred at −15° C. for 20 min to dissolve all the solids. The yellow solution was then brought back to −40° C. and 3,3-dimethylcyclobutanecarbonyl chloride (Intermediate 22) (450 mg, 3.07 mmol) was added dropwise. The color changed from slightly green to yellow, then red, then yellow. The mixture was warmed to 0° C. over 2 h in the same bath. The mixture was diluted with 1 N HCl and extracted with ethyl acetate (3 times). The combined organic layers were washed with brine, dried over Na2SO4, and concentrated in vacuo. The crude material was partially purified by silica gel flash chromatography (ethyl acetate/heptane) to give impure 4-(3,3-dimethyl-cyclobutanecarbonyl)-benzoic acid ethyl ester (588 mg). 1H NMR (400 MHz, CDCl3) δ 8.11 (d, J=8.4 Hz, 2 H) 7.94 (d, J=8.4 Hz, 2 H) 4.38-4.48 (m, 2 H) 3.90 (quin, J=8.8 Hz, 1 H) 2.16-2.29 (m, 2 H) 2.04-2.13 (m, 2 H) 1.42 (t, J=7.2 Hz, 3 H) 1.28 (s, 3 H) 1.09 (s, 3 H); MS (M+1): 261.4.

Procedure:
To a tetrahydrofuran solution (10 mL) of 1-benzhydrylazetidin-3-one (530 mg, 1.94 mmol), methylmagnesium iodide (0.84 M ether solution) (4.62 mL, 3.88 mmol) was added at 0° C. under a nitrogen stream, and the mixture was stirred for one hour at the same temperature. A saturated aqueous solution of sodium hydrogen carbonate (20 mL) was added to the reaction liquor, and the mixture was stirred for 15 minutes. Then, the reaction liquor was filtered through celite, and the filtrate was extracted with ethyl acetate. The extract was washed with saturated brine, and then dried over anhydrous sodium sulfate. Sodium sulfate was separated by filtration, and the solvent was concentrated under reduced pressure. The obtained residue was purified by flash chromatography (Flash Chromatography System from Biotage AB, column size: 40S, ethyl acetate/n-hexane=1/4 to ethyl acetate), to obtain the title compound (511 mg, quant.) as an oily matter.

Procedure:
2-Chloro-4-iodo-pyridine (10.0 g, 41.8 mmol) was dissolved in 200 mL dry THF and 17.5 mL triethyl amine. This mixture was evacuated and backfilled with argon several times to remove oxygen from the solution. Triphenylphosphine (329 mg, 1.25 mmol) and bis(triphenylphosphine)palladium(II) chloride (1.47 g, 2.09 mmol) were added and the reaction mixture was stirred at room temperature for 1 h. Copper(I) iodide (239 mg, 1.25 mmol) and trimethylsilylacetylen (6.28 g, 6.39 mmol) were added. The reaction mixture was stirred at room temperature overnight. The solvent was evaporated. The residue was taken up in 500 mL water and extracted three times with ethyl acetate (500 mL each). The combined organic extracts were dried with magnesium sulfate, filtered and evaporated. The crude product was purified by chromatography on silica gel (cyclohexane/ethyl acetate 80:20). The desired product was obtained as a light brown semi solid (10 g, >100%). This material was used without any further purification for the next step.
