실험 절차

2-(3-(7-Amino-6-bromo-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetic acid was synthesized in a manner similar to the synthesis of 2-(4-(7-amino-6-bromo-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetic acid, but with ethyl 2-(3-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate substituted for ethyl 2-(4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate. The reaction was concentrated in vacuo and purified via reverse-phase preparatory HPLC to yield 2-(4-(7-amino-6-bromo-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetonitrile as a four-isomer mixture. (m+H=480.1, retention time=3.51 min)
