Procedure:
To a solution of the 1-monofluoro-2-decyl 4-hydroxybenzoate prepared in (1) (0.1 g) and triethylamine (0.04 g) in methylene chloride (10 ml) was slowly added under ice cooling a solution of 4-n-octyloxybenzoic acid chloride (0.1 g) in methylene chloride (10 ml). The mixture was left to stand until it reached room temperature and stirred overnight. The mixture was poured in water and extracted with methylene chloride. The extracted layer was washed with dilute aqueous hydrochloric acid solution, water, 1N aqueous sodium carbonate solution and water, in this order, and dehydrated over anhydrous magnesium sulfate. After the solution was distilled under reduced pressure to remove the solvent, the product was purified by silica-gel column chromatography to obtain the titled compound (0.13 g).

The reaction mixture was poured into ice water, and the mixture was neutralized with saturated aqueous sodium hydrogen carbonate solution, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (101 mg).

Procedure:
Dibenzylphosphoryl-L-alanyl-L-proline (1.2 g, 2.5 m mole), HOBt (338 mg, 2.5 m mole) and L-tyrosine ethylester hydrochloride (737 mg, 3 m mole) was suspended in DMF (10 ml), and WSC (0.5 ml) was added gradually thereto while cooling to -15° C. and stirring. The reaction was carried out for 3 hours under cooling and then overnight at room temperature. To the reaction solution ethyl acetate (100 ml) was added, and the mixture was washed with 1N hydrochloric acid and water in order, and dried with anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure to obtain an oily dibenzylphosphoryl-L-alanyl-L-prolyl-L-tyrosine ethylester (1.4 g). This oily material gave a single spot with Rf 0.50 by thin layer chromatography (developing solvent; chloroform:methanol:acetic acid=95:5:3, colour forming method: spraying of 25% hydrobromic acid and 0.1% ninhydrine, and heating).

Procedure:
Compound 7 (357 mg, 0.904 mmol), 2-methoxybenzylamine (189 mg, 1.38 mmol) and camphorsulfonic acid (2.0 mg) were dissolved in toluene (30 ml), and the resultant mixture was heated at reflux for 3 days under a dehydrating condition with MS 4A. After replacement of the solvent with THF a solution of 9-BBN (0.5M in THF, 5.4 ml) was added, and the resultant mixture was stirred for 4 days at room temperature. After evaporation of the solvent the residue was basified at pH=13, extracted with CH2Cl2, dried over Na2SO4, and concentrated down. The crude material was purified by combination of column chromatography (silica-gel, MeOH/CH2Cl2), preparative TLC (silica-gel, 10% MeOH/CH2 Cl2) and crystallization from MeOH to provide pure compound 8 (109 mg, 23%).
