Procedure: A mixture of 4-borono-2-fluorobenzoic acid (218 mg, 1.2 mmol), (3-(methylsulfonyl)phenyl)-methanamine (200 mg, 1.08 mmol), DIEA (0.754 mL, 4.32 mmol) and TBTU (381 mg, 1.2 mmol) in DMF (2 mL) was stirred at room temperature for 2 days, then the reaction mixture was diluted with water (10 mL), and product precipitated out as gum, and the supernatant was separated via centrifugation, and the gummy residue was sonicated with water (3 mL), and the gummy residue was further dried under high vacuum yielding 3-fluoro-4-(3-(methylsulfonyl)benzylcarbamoyl)-phenylboronic acid (335 mg, 88%) as white foam. LCMS (m/z): 352.1 (MH+), 0.51 min. precipitated out as gum the supernatant was separated via centrifugation the gummy residue was sonicated with water (3 mL) the gummy residue was further dried under high vacuum

Procedure: Reaction of 2,4-dichloro-5-(trifluoromethyl)pyrimidine XL with commercially available 1-[3-(methylsulfonyl)phenyl]methanamine and diisopropylethylamine at 0° C. overnight affords a mixture of 2-chloro-N-[3-(methylsulfonyl)benzyl]-5-(trifluoromethyl)pyrimidin-4-amine and 4-chloro-N-[3-(methylsulfonyl)benzyl]-5-(trifluoromethyl)pyrimidin-2-amine XLIVa/XLIVb. The crude mixture was crystallized from methylene chloride to afford a sample of the pure, undesired 2-substituted isomer XLIVb. The mother liquors were chromatographed over silica gel eluting with 1:1 hexane:ethyl acetate to yield a further pure sample of the 2-substituted isomer plus a sample of the desired 2-chloro-N-[3-(methylsulfonyl)benzyl]-5-(trifluoromethyl)pyrimidin-4-amine XLIVa. Reaction of this latter isomer with anilines such as diethyl (4-aminobenzyl)phosphonate in the presence of TFA and TFE under microwave irradiation yields the desired product (e.g. diethyl (4-{[4-{[3-(methylsulfonyl)benzyl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}benzyl)phosphonate, Ex. 25). affords The crude mixture was crystallized from methylene chloride to afford a sample of the pure, undesired 2-substituted isomer XLIVb The mother liquors were chromatographed over silica gel eluting with 1:1 hexane ethyl acetate to yield a further pure sample of the 2-substituted isomer under microwave irradiation
