Procedure:
14.5 g of 1-(N-benzyl-tert.-butylamino)-3-(3-amino-2-hydroxy-phenoxy)-2-propanol are dissolved in 140 ml of an isopropanol/water mixture (1:1) and 5.0 ml of methyl chloroformate are added, at 15°-20°, whilst stirring vigorously and stirring is continued for a further 11/2 hours at room temperature, the reaction mixture is then evaporated and the residue is dissolved in 50 ml of water. After extraction with 20 ml of ethyl acetate, the acid aqueous phase is rendered alkaline with concentrated sodium hydroxide solution and extracted with 3 times 100 ml of methylene chloride. Evaporation of the organic phase gives the crude base, from which crystalline 1-(N-benzyl-tert.-butylamino)-3-(2-hydroxy-3-methoxycarbonylamino-phenoxy)-2-propanol with a melting point of 130°-133° is isolated.

Procedure:
1-(3-Amino-7-benzyloxyquinolin-4-ylamino)-2-methyl-propan-2-ol (25 g, 74.09 mmol) was added to 500 mL of pyridine. To this mixture was added in a dropwise manner a solution of methoxypropionyl chloride (10 g, 81.5 mmol) dissolved in 20 mL of toluene. After approximately half of the acid chloride had been added, the reaction mixture became completely homogenous. Two hours after the addition of the acid chloride, the reaction mixture was heated to reflux and maintained overnight. The solvent was concentrated through the use of a Dean-Stark trap. Cooling to ambient temperature provided a white precipitate, which was collected by filtration. The solid was slurried in 1 L of 1% hot aqueous sodium carbonate (75-80° C.) for 1 hour. The mixture was then cooled in an ice bath and the solid material was filtered, rinsed with water, and dried to yield 22.7 g of 1-[7-benzyloxy-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol as a white solid, mp 170-171.5° C.

Procedure:
To a solution of 6-(2-methoxycarbonylamino-3-methyl-butyryl)-5-oxa-6-aza-spiro[3.4]octane-7-carboxylic acid ethyl ester (1.31 g, 3.83 mmol) in ethanol (10 mL) was added a solution of lithium hydroxide (1M in water, 7.6 mL, 7.6 mmol). The reaction was stirred at room temperature for 30 minutes. The reaction was partially concentrated and the resulting aqueous solution was washed with ethyl acetate. The ethyl acetate layer was discarded and the aqueous layer was acidified using concentrated HCl. The acidic aqueous layer was extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried (MgSO4) and concentrated to yield crude 6-(2-methoxycarbonylamino-3-methyl-butyryl)-5-oxa-6-aza-spiro[3.4]octane-7-carboxylic acid, which was used without further purification.

Procedure:
3.83 g 4-dimethylamino-4-phenylcyclohexanone dissolved in 10 ml tetrahydrofuran were added dropwise to 21 ml 1.0 molar phenethyl magnesium chloride solution in tetrahydrofuran and the mixture was stirred overnight at ambient temperature. To work up the mixture with ice cooling, 15 ml ammonium chloride solution (20% by weight) were added, the mixture was extracted three times with 15 ml ethylacetate in each case, the extracts were combined, dried over sodium sulfate, filtered, concentrated and substantially freed of solvent residues under vacuum. The crude 4-dimethylamino-1-phenethyl-4-phenylcyclohexanol (5.75 g) obtained was obtained as a brown oil which was chromatographed with diethylether/hexane (V:V=1:1) over silica gel. 1.71 g 4-dimethylamino-1-phenethyl-4-phenylcylcohexanol were obtained in the form of yellow crystals which were dissolved in 6.8 ml 2-butanone and converted by reaction with 26 μl water and 366 μl chlorotrimethylsilane, stirring overnight with subsequent filtration into 838 mg of the corresponding hydrochloride.

Procedure:
The compound of formula (43) can be prepared from 3-butynyl p-toluenesulfonate (42) and 2(R)-methylpyrrrolidine L-tartrate (40) as shown in Scheme 5. 2(R)-Methylpyrrolidine L-tartrate (40) is treated with potassium carbonate in acetonitrile to provide 2(R)-methylpyrrolidine (41), which is combined with 3-butynyl p-toluenesulfonate (42) to give 1-but-3-ynyl-2-methyl-pyrrolidine (43). Compound (43) is reacted with 4-bromo-2-iodo-phenylamine (44) to provide 4-bromo-2-[4-(2-methyl-pyrrolidin-1-yl)-but-1-ynyl]-phenylamine (45). Compound (45) undergoes cyclization to compound (46) in the presence of a strong base, such as potassium t-butoxide. Compound (46) then is subjected to the Suzuki reaction conditions with an aryl or heteroaryl boronic acid, such as 4-cyanophenylboronic acid, to give compound (47) and (47a). Alternatively, in the presence of base and an alkylating agent, compounds (45) and (46) are alkylated with an alkyl halide such as methyl iodide to give an N-alkyl indole compounds, such as compound (48). Compound formula (48) is then subjected to the Suzuki reaction conditions with an aryl or heteroaryl boronic acid, such as 4-cyanophenylboronic acid, to give compounds such as compound (49) and (49a). Similarly, the compounds (40) and (41) can be substituted with any other suitable amine to provide the corresponding amine-substituted indole compound. In addition, the 4-cyanophenylboronic acid can be substituted with other boronic acids of the formula RcB(OH)2, wherein Rc is aryl or heteroaryl, to provide compounds of general structures (47a) and (49a), wherein R1 is aryl, heteroaryl, or heterocycle.

Procedure:
Powdered iodine (1 eq.) was added to a stirred solution of triphenylphosphine (1.15 eq.) in dry acetonitrile (10 ml/mmol of sulfoxide to be used) in a nitrogen atmosphere. The mixture was stirred until the iodine color was no longer present and a yellow colored suspension had formed. The sulfoxide (IX) (1 eq.) in dry acetonitrile (2.5 ml/mmol sulfoxide) was added in one portion. This was immediately followed by adding the solid powdered sodium iodide (2 eq.). The mixture was stirred and rapidly changed to a dark color. TLC showed that the reaction was complete after 1 min. After stirring for no more than 5 min. the solution was poured into a mixture of 5% sodium thiosulfate solution and ether. The mixture was shaken until the iodine color had disappeared, the ether phase was separated and washed with a 5% sodium bicarbonate solution. The ether solution was dried over sodium sulfate and evaporated in vacuo. The crude material was passed through a short column of silica gel (30 g/g of crude product) using dichloromethane. The excess triphenylphosphine came off with the solvent front and was followed almost immediately by the product compound (X). The sulfide (X) was obtained as an oil which was sufficiently pure to be used in the next step.

Procedure:
1.42 g (20 mmol) of azetidine-2-one was added with 1.81 g (22 mmol) of anhydrous sodium acetate, 6.4 g of acetic acid, 5.6 g of ethyl acetate and 0.678 g (2 mmol) of benzene ruthenium dibromide, cooled to 5°-10° C., then added dropwise with 16.5 g of acetic acid solution containing 22% peracetic acid over 1.5 hours while stirring. After the dropping, a further 15 hour stirring was conducted at the same temperature. The solvent was distilled off under reduced pressure, followed by purification by silica gel column chromatography (hexane/ethyl acetate=1/1 by volume) to obtain 1.67 g of 4-acetoxyazetidine-2-one (yield: 65%).
