The invention is based on the discovery that compounds of Formula I are unexpectedly highly potent and selective inhibitors of the adenosine A
1
receptor. Adenosine A
1
antagonists can be useful in the prevention and/or treatment of numerous diseases, including cardiac and circulatory disorders, degenerative disorders of the central nervous system, respiratory disorders, and many diseases for which diuretic treatment is suitable.
In one embodiment, the invention features a compound of formula I:
A purification method of a phosphoric ester, which comprises treating a crude phosphoric ester with an epoxy compound, heating the resultant in the presence of water, washing the resultant with water, and removing the residual water. The obtained phosphoric esters have low acid value and are excellent in physical properties such as heat resistance, resistance to hydrolysis and storage stability, and are useful as plasticizers and/or flame-retardants.
