Procedure
Ethyl 4-((S)-(2,4-difluorophenyl)(4-hydroxy-2-(1H-pyrazol-1-yl)pyrimidine-5-carboxamido)methyl)phenyl(methyl)phosphinate, 21-e, (400 mg, 0.78 mmol) was dissolved in 2 ml of dioxane and treated with 0.2 ml of 5N NaOH. The mixture was heated at 80° C. for 30 min. Then the mixture was concentrated under vacuum. The residue was diluted with water and washed with ethyl acetate. The aqueous layer was acidified with AcOH and evaporated to dryness. The residue was used for prep-HPLC to afford the product, 21-1, (250 mg, 66%). 1H NMR (300 MHz, CD3OD): δ 8.67 (s, 1H), 8.58 (s, 1H), 7.92 (s, 1H), 7.81 (m, 2H), 7.48 (m, 3H), 7.01 (m, 2H), 6.66 (s, 1H), 6.60 (s, 1H), 1.67 (d, 3H). (M−H)−=484.0.
