Participants

Reaction Steps

A mixture of 1-tert-butyl-6-(2-propoxyphenyl)pyrazolo[3,4-d]pyrimidin-4-one 1/100 hydrate (0.68 g, 2.1 mmol) and trifluoroacetic acid (50 ml) was heated on a steam bath for 3.5 hours. The reaction mixture was stripped to dryness and the residue was purified by column chromatography on silica gel eluting with ether to afford 0.45 g (79%) of 6-(2-propoxyphenyl)pyrazolo[3,4-d]pyrimidin-4-one 1/4 hydrate, m.p. 170°-171° C.
