Procedure:
A solution of the product of Example 66B (12.8 g, 51.2 mmol) in ethylene glycol (200 mL) was heated at reflux for 6 hours, cooled to ambient temperature, stirred for 16 hours at ambient temperature, then heated at reflux for an additional 3 hours.

Procedure:
[2-(2-Nitro-5-trifluoromethylphenyl)-1-(4-methoxyphenyl)ethyl]propanedioic acid, dimethyl ester (46.54 g; 0.102 mole; see Example 4A) was dissolved in dry dimethylformamide (290 ml) under argon. Fifty percent sodium hydride (5.89 g; 0.123 mole; prewashed-hexane) was added with stirring which was continued for 20 minutes before allyl bromide (44 ml; 61.7 g; 0.510 mmole; d=1.398; 5 eq.) was added dropwise. After six hours, 40 minutes, the reaction was quenched with 1N hydrochloric acid. The solution was extracted with ethyl acetate (two times) and the extract was washed with 1N hydrochloric acid (two times), saturated potassium carbonate (two times), saturated sodium chloride, and dried (magnesium sulfate). The concentrated solution (viscous oil) was flash chromatographed (silica gel/9:1-hexane: ethyl acetate, followed by 8:2-hexane:ethyl acetate) in two portions. After drying in vacuo overnight, the yellow viscous oil product weighed 54.77 g. The product was used "as is" in the next step.

Procedure:
To a suspension of methyl 6-(7-cyclopentyl-6-(dimethylcarbamoyl)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)nicotinate (2.0 g, 4.9 mmol) in THF (6 mL) was added 1M LiOH (aq) (6 mL, 1.2 equiv) and the slurry stirred at 45° C. for 12 hours (the slurry became clear). After cooling to room temperature, the THF was evaporated and the reaction mixture was treated with 1 N HCl until pH=1-2. The resulting precipitate was filtered and the filtrate extracted with 20% Isopropanol/CH2Cl2 (3×100 mL), the combined organic layers dried, filtered, and concentrated to a tan solid. The tan solid was triturated in acetone giving 6-(7-cyclopentyl-6-(dimethylcarbamoyl)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino) nicotinic acid as the desired product as a tan solid (1.56 g, 73% yield) which was used without further purification.
