Procedure:
In a first step, dodecyl bromide (767 μL, 3.2 mmol), NaI (478 mg, 3.2 mmol) and NaH (76 mg, 3.2 mmol) were added to a solution of 8-hydroxyl-quinoline-2-carboxylic acid methyl ester (2.11 mmol) stirring in DMF (dry, 10 mL), and the red reaction was allowed to stir overnight. The crude material resulting from removal of solvents by rotary evaporation was taken into DCM, washed with water, dried over Na2SO4, and filtered. The resulting solution was evaporated to dryness and the desired intermediate, 8-dodecyloxy-quinoline-2-carboxylic acid methyl ester, was obtained by HPLC (isocratic, 75% acetonitrile, 25% water) yielding 169 mg (about 14% yield). This intermediate was in turn deprotected using LiOH in THF/H2O as described in the method of Example 336 to yield the title compound, which was utilized further without additional purification or characterization.

Procedure:
6-Trifluoromethyl-9-methyl-2-phenethylaminopurine (compound 10) (0.500 g, 1.56 mmol) was dried in vacuo at 100° C. for 2.5 h. After cooling, dry THF (18 ml) was added at room temperature and the solution was cooled to −72° C. (ethanol/dry ice). After addition of n-BuLi (2.4 ml of a 1.6 M solution in hexane, 3.9 mmol) the colourless solution turned yellow. After 15 minutes I2 (0.633 g, 2.49 mmol) was added and after 5 minutes the reaction was complete (HPLC: Rt,product=4.7). To the red solution silica gel (˜4 g) was added and the suspension was evaporated to dryness. Flash chromatography (1% MeOH in MTBE) and freezedrying afforded the product (0.637 g, 91%) as fluffy white crystals, mp 139-142° C. 1H-NMR (400 MHz, CDCl3), δ [ppm]: 7.33-7.21 (m, 5H, Har), 5.96 (br s, 1H, NH), 3.93 (br m, 2H, NHCH2), 3.77 (s, 3H, CH3), 2.98 (t, J=7.1 Hz, 2H, CH2). 19F-NMR (500 MHz, CDCl3), δ [ppm]: −70.12 (6-CF3).

Procedure:
To a solution of 5-bromo-2-chloro-N4-ethyl-pyridine-3,4-diamine (II, 550 g, 2.21 mol) in CH2Cl2 (5.5 L) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (634.5 g, 3.31 mol), cyanoacetic acid (282 g, 3.31 mol) and N-methylmorpholine (897 g, 8.84 mol). A significant exotherm (˜20° C.) was observed upon the addition of the 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and cyanoacetic acid. After stirring at ambient temperature for 2 h, the solvent was removed under reduced pressure. The resulting reside was extracted with warm EtOAc (40° C., 20 L) and water (40° C., 8 L). The aqueous layer was washed with addition EtOAc (10 L) and the combined organic extracts were washed with water (10 L). The organic extract was concentrated under reduced pressure to a slurry and filtered. The solid was washed with EtOAc and dried to give 534 g (76% yield) of the desired compound (III) as a white crystalline solid. This was used in the next step without further purification.
