Procedure:
Di-tert-butyl 1-(3-ethyl-2,3-dihydro-1H-inden-5-yl)hydrazine-1,2-dicarboxylate 41c (3.43 g, 9.1 mmol) was dissolved in 50 mL of a solvent mixture of ethanol/water (V:V=3:2) followed by addition of 3-oxo-butanoic acid ethyl ester (1.18 g, 9.1 mmol) and 4.55 mL of hydrochloric acid (6 N). Upon completion of the addition, the reaction mixture was heated to reflux and reacted for 1 hour. The reaction was monitored by TLC until the disappearance of the starting materials. The mixture was concentrated under reduced pressure to remove ethanol and then extracted with dichloromethane (15 mL×3). The combined organic extracts were dried over anhydrous sodium sulfate, filtered to remove the drying agent and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound 2-(3-ethyl-indan-5-yl)-5-methyl-2,4-dihydro-pyrazol-3-one 41d (0.712 g, 39.8%) as a yellow oil.

Procedure:
A mixture containing 16.32 g (0.08 mol) of 6-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carboxylic acid and 12.4 ml (0.088 mol) of triethylamine in 480 ml of chloroform is cooled below -10° C. by ice-salt. A solution of 6.5 ml (0.08 mol) of methyl chloroformate in 40 ml of chloroform is dropped to the above mixture at a temperature between -13° C. and -16° C. during 25 minutes. After stirring for 5 minutes, 11.37 g (0.088 mol) of octylamine dissolved in 80 ml of chloroform are dropped to the above solution at a temperature between -13° C. and -16° C. during 40 minutes. The reaction mixture is stirred at the same temperature for 1 hour and then allowed to stand overnight under cooling by ice. For working up, the reaction mixture is washed 3 times with 150 ml of 5% sodium hydrogen carbonate solution each and then 3 times with 150 ml of water each. The organic phase is dried over anhydrous sodium sulfate, filtered and evaporated to obtain 15.4 g (61.0%) of the named product as yellow crystals after recrystallization from ethanol, m.p.: 108°-110° C.

Procedure:
To 122 mg of the obtained methyl 3-{[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]carbonyl}benzoate were added 2.0 mL of THF, 1.0 mL of methanol, and 1.0 mL of a 1 M aqueous sodium hydroxide solution, followed by stirring at room temperature overnight. It was neutralized by addition of 1.1 mL of 1 M hydrochloric acid, and then extracted with ethyl acetate, and the organic layer was dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure, and dried to obtain 3-{[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]carbonyl}benzoic acid as a crude product (colorless foamy substance, 121 mg).

Procedure:
To a stirred solution of 3,5-dimethoxypyridine (2.7 g, 19.4 mmol) in dry THF at −78° C. was added n-butyllithium (23.3 mmol, 2 M solution in cyclohexanes). During this addition a precipitate formed and the reaction was allowed to warm to room temperature for 5 minutes. The precipitate separated into an oily phase and the reaction was re-cooled and treated with bromine (1.5 ml, 29.1 mmol) and again allowed to warm to room temperature. After stirring for 10 minutes the solution became homogeneous and was quenched with 10% Na2S2O3 (aq) and extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4 and concentrated onto silica-gel under reduced pressure. The solid residue was purified by flash chromatography (silica-gel, eluted sequentially with hexanes:EtOAc, 2:1, 1:1, 1:2) to give the product as a white solid (2.4 g, 57%). 1H-NMR (300 MHz, CDCl3) δ 7.95 (s, 2H), 3.99 (s, 6H).

Procedure:
Into a 12-liter, three-necked round bottom flask equipped with mechanical stirrer, addition funnel, thermocouple, heating mantle, N2 inlet, and temperature controller were charged 1,021 grams of 3-mercaptopropyltriethoxysilane (SILQUEST® A-1891 silane from Crompton Corp.), 433 grams of triethylamine, and 3,000 mL of hexane. The solution was cooled in an ice bath, and 693 grams of octanoyl chloride were added over a two hour period via the addition funnel. After addition of the acid chloride was complete, the mixture was filtered two times, first through a 0.1 :m filter and then through a 0.01 :m filter, using a pressure filter to remove the salt. The solvent was removed under vacuum. The remaining yellow liquid was vacuum distilled to yield 1,349 grams of octanoylthiopropyltriethoxysilane as a clear, very light yellow liquid. The yield was 87 percent.
