Procedure: Lithium bis(trimethylsilyl)amide (32.3 g, 193 mmol) was added to 80 mL of tetrahydrofuran and the resulting solution was cooled in an ice bath. Addition of a solution of 2-phenyl-propionic acid (11.6 g, 77.3 mmol) in 10 mL of tetrahydrofuran to the reaction solution was followed by addition of 1-bromo-3,3-dimethyl-butane (20.4 g, 124 mmol). The reaction vessel was removed from the cooling bath, placed in a 50° C. oil bath, and the reaction solution was stirred for 17 hours. After concentration, the resulting residue was dissolved in 250 mL of 1 N NaOH, washed with 250 mL of 2:1 hexane/iso-propyl acetate, acidified to pH 1 with 6 N HCl, and extracted with ethyl acetate (3×300 mL). The combined organic layers were dried over Na2SO4 and concentrated to give 17.3 g (96%) of clear oil. 1H NMR (300 MHz, CDCl3): δ ppm 0.86 (s, 9H) 1.09 (m, 2H) 1.56 (s, 3H) 1.99 (m, 2H) 7.33 (m, 5H). the resulting solution was cooled in an ice bath The reaction vessel was removed from the cooling bath placed in a 50° C.

Procedure: A solution of the compound of Example 22A (11.75 g, 64.6 mmol) in tetrahydrofuran (30 mL) was added dropwise over 20 min to a −78° C. solution of lithium hexamethyldisilazide (previously prepared from hexamethyldisilazane (17.0 mL, 80.7 mmol) and n-butyllithium in hexane (2.5 M, 31.0 mL, 77.5 mmol)) in tetrahydrofuran (40 mL) and allowed to stir at that temperature for 1 h. The solution was then treated with 1-bromo-3,3-dimethylbutane (12.0 mL, 83.9 mmol), followed by stirring at −78° C. for 30 min, and then warming to 25° C. for 18 h. The solution was quenched by addition of saturated ammonium chloride solution (4 mL) and then concentrated in vacuo. The residue was diluted with ethyl acetate and water. The organic layer was extracted with water (2×), saturated NaCl solution and dried (Na2SO4). Concentration in vacuo afforded an oil, which was distilled under reduced pressure (90-93° C./0.3 mm Hg) to afford the product (4.85 g, 28%) as a colorless oil. 1H NMR (300 MHz, CDCl3): δ 0.86 (s, 9 H) 1.03 (m, 2 H) 1.51 (m, 3 H) 1.86 (m, 1 H) 2.00 (m, 1 H) 3.65 (m, 3H) 7.03 (m, 2 H) 7.27 (m, 2 H). by stirring at −78° C. for 30 min The solution was quenched by addition of saturated ammonium chloride solution (4 mL) concentrated in vacuo The residue was diluted with ethyl acetate and water The organic layer was extracted with water (2×), saturated NaCl solution dried (Na2SO4) Concentration in vacuo afforded an oil, which was distilled under reduced pressure (90-93° C./0.3 mm Hg)
