実験手順
tert-Butyl 4-(7-hydroxypyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1-carboxylate was synthesized in a manner similar to the synthesis of 5-(1,4-dioxaspiro[4.5]decan-8-yl)pyrazolo[1,5-a]pyrimidin-7-ol, but with tert-butyl 4-(3-ethoxy-3-oxopropanoyl)piperidine-1-carboxylate substituted for ethyl 3-oxo-3-(1,4-dioxaspiro[4.5]decan-8-yl)propanoate.
