実験手順

To a solution of 1-(2-fluorobenzyl)-N-(1H-pyrazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine (Example 88), (111 mg, 0.36 mmol) in ACN/H2O (9:1, 4 mL) was added potassium cyanate (35 mg, 1.2 eq). After 30 min at rt, the reaction mixture was neutralized with saturated sodium carbonate and the aqueous phase extracted with DCM. The combined organic phases were dried over sodium sulfate and concentrated in vacuo. The residue was purified by preparative HPLC to give the title product. 1H NMR (d6-DMSO) δ 10.12 (s, 1H), 9.00 (s, 1H), 8.57 (s, 1H), 8.12 (s, 1H), 7.94 (s, 1H), 7.80 (s, 1H), 7.71 (s, 1H), 7.41-7.28 (m, 2H), 7.26-7.14 (m, 2H), 5.58 (s, 2H); LC-MS method B, (ES+) 353.0, RT=7.75 min.
