p-Toluenesulfonic acid → HCID 57818943, compound

Participants

Reaction Steps

To a mixture of [5-fluoro-2-(4-fluorobenzyloxy)pyrimidin-4-ylamino]methanol (0.10 g, 3.7 mmol) in benzyl alcohol (1 mL) was added a catalytic amount of p-toluene sulfonic acid. After 30 min, the reaction was cooled to room temperature and partitioned between ethyl acetate and saturated sodium bicarbonate. The phases were separated and the organic portion was dried over anhydrous Na2SO4, filtered and evaporated to obtain the crude product. Purification by reverse phase chromatography afforded 0.094 g (70%) of the title compound as a white solid: mp 64-66° C.; 1H NMR (CDCl3) δ 7.93 (d, J=2.7 Hz, 1H), 7.47-7.40 (m, 2H), 7.37-7.29 (m, 5H), 7.08-7.00 (m, 2H), 5.81-5.70 (bm, 1H), 5.29 (s, 2H), 5.12 (d, J=6.9 Hz, 2H), 4.63 (s, 2H); MS (ESI) m/z 358 (M+H)+.
