Procedure

5-(1,4-dioxaspiro[4.5]decan-7-yl)pyrazolo[1,5-a]pyrimidin-7-ol 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 ethyl 3-oxo-3-(1,4-dioxaspiro[4.5]decan-7-yl)propanoate substituted for ethyl 3-oxo-3-(1,4-dioxaspiro[4.5]decan-8-yl)propanoate.
