Procedure

To a solution of 4-hydroxy-2-(1H-pyrazol-1-yl)pyrimidine-5-carboxylic acid, 8-b, (309 mg, 1.5 mmol) in MeCN (10 ml) were added HATU (599 mg, 1.58 mmol), Et3N (159 mg, 1.58 mmol) and diethyl 4-(amino(phenyl)methyl)phenylphosphonate, 2-c, (479 mg, 1.5 mmol). The resulting mixture was stirred at room temperature for 2 hours. Then it was concentrated under vacuum and the residue was taken into ethyl acetate followed by washing with sat. NH4Cl. The organic layer was dried over sodium sulfate and concentrated under vacuum. The residue was purified by prep-HPLC to provide the product, 8-1, (150 mg, 20%). 1H NMR (CD3OD, 300 MHz,): δ 10.39 (br, 1H), 8.56 (s, 1H), 8.47 (m, 1H), 7.81 (m, 1H), 7.62 (m, 2H), 7.40 (m, 2H), 7.25 (m, 5H), 6.54 (m, 1H), 6.26 (m, 1H), 3.96 (m, 4H), 1.18 (m, 6H).
