Procedure:
A mixture of 6-(4-fluorophenoxy)-8-methyl-2-(methylsulfonyl)pyrido[2,3-d]pyrimidin-7(8H)-one (see Example 8 replacing methyl 2-fluorophenoxyacetate with methyl 4-fluorophenoxyacetate-Step A-B, 0.35 g, 1 mmol) and 4-fluoroaniline (0.284 mL, 3 mmol) in 0.5 mL 1-methyl-2-pyrrolidinone was stirred at 110° C. for 12 hours and then cooled to room temperature. Methanol (2 mL) was added and the suspension was stirred for 30 minutes. Filtration and washing of the precipitate thoroughly with methanol followed by drying provided the crude product which was purified by column chromatography (SiO2, CH2Cl2/MeOH—95/5). The column fractions were combined and concentrated under reduced pressure to provide the free amine. This was suspended in ethyl acetate (1-2 mL) and hydrochloric acid in ether (1M, 1.2 eq) was added. Isolation of the solid via filtration and drying provided 0.101 g of the hydrochloride salt (Mass spec. M+1=381, MP=242.3-242.6° C.).

Procedure:
16-Hydroxyhexadecanoic acid (6.81 g, 25.0 mmol) was dissolved in tetrahydrofuran (150 ml) and the solution was cooled to 0° C. before adding pyridine (2.73 g, 34.5 mmol).

Procedure:
To a solution of 3-hydroxymethyl-2-methylpyridine (10.42 g) in toluene (100 ml) was added dropwise thionyl chloride (9.87 ml) at 25° C. After 2.5 hours, the solvent was removed in vacuo to give a residual solid. The solid was dissolved in 4N-aqueous sodium hydroxide (100 ml) and extracted with ethyl acetate. The organic layer was separated, washed with brine and dried over magnesium sulfate. Concentration of the solution gave 3-chloromethyl-2-methylpyridine (9.22 g).

Procedure:
To an ice-cooled solution of 2,6-dimethylphenol (12.2 g, 0.1 mmol) in dichloromethane, anhydrous aluminum chloride (14.4 g) was slowly added with stirring, followed by slow addition of acetyl chloride (9.4 g). The reaction mixture was stirred at 10° C. or below for 1 h, then at room temperature for 3 h. Thereafter, the mixture was poured into ice water. Then, the reaction product was extracted with dichloromethane and the extracted layer was washed with water. Further, the extracted layer was dried over anhydrous sodium sulfate and the solvent was distilled off under reduced pressure. The residue was recrystallized with benzene, giving the desired compound, 2,6-dimethyl-4-acetylphenol in an amount of 1.9 g.

Procedure:
1,4,7,10-Tetraazacyclododecane-4,7,10-triacetic acid tri-t-butyl-ester (515 mg, 1 mmol) was dissolved in dimethylformamide (3 ml). Sodium iodide (15 mg, 0.1 mmol), triethylamine (233 mg, 2.5 mmol) and 2(2-chloroethoxy)ethanol (313 mg, 3.5 mmol) were added to the stirred mixture at ambient temperature. The mixture was stirred for 18 hours at ambient temperature. The temperature was then raised to 100° C. and kept there for 1 hour. The solvent was then evaporated and the residue dissolved in a mixture of dichloromethane (4.5 ml) and trifluoroacetic acid (4.5 ml). The mixture was stirred for 2 hours at ambient temperature and the solvent was then evaporated. The residue was dissolved in water (8 ml), and this aqueous solution was washed with ether (6-4 ml). The aqueous solution was acidified and the title compound was isolated as a hygroscopic white powder after evaporation of the water. Yield 325 mg (75%), FAB MS: 435(M+1). The structure was confirmed by 1HNMR and 13C NMR.

Procedure:
In 200 ml of methylene chloride was dissolved 21 g of the 3-(benzyloxycarbonylamino)propanol, and 11 g of triethylamine was added thereto, after which 8.6 g of acetyl chloride was added thereto dropwise at -10° C. to -5° C. The resulting mixture was subjected to reaction at the same temperature for 1 hour. Subsequently, at room temperature, the reaction mixture was washed successively with 50 ml of diluted hydrochloric acid, 50 ml of a saturated aqueous sodium hydrogencarbonate solution and 50 ml of water, and then dried over anhydrous magnesium sulfate, after which the solvent was removed by distillation under reduced pressure to obtain 28 g of oily 1-acetoxy-3-(benzyloxycarbonylamino)propane.
