Participants

Reaction Steps

1-tert-butyl-3-(3-(benzyloxy)phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (19 mg, 0.052 mmol) was dissolved in a solution of formic acid (1 mL) and conc. HCl (0.1 mL) and heated to reflux for 30 min. Reaction yielded a mixture of ZK136 and 3-(4-amino-1H-pyrazolo[3,4-d]pyrimidin-3-yl)phenol (ZK138). Reaction was concentrated in vacuo and the products purified by RP-HPLC (MeCN:H2O:0.1% TFA). ZK136: ESI-MS (M+H)+ m/z calcd 318.1, found 318.3. ZK138: ESI-MS (M+H)+ m/z calcd 228.1, found 228.3.
