Procedure

A stirred and warm suspension of 4 parts of 6-[2-[4-(1H-indol-3-yl)-1-piperidinyl]ethyl]-3,7-dimethyl-5H-thiazolo[3,2-a]pyrimidin-5-one in 80 parts of ethanol was acidified with phosphoric acid. 60 Parts of water were added and the whole as boiled. The undissolved material was filtered off and the filtrate was allowed to crystallize. The product was filtered off and dried, yielding 4.5 parts (80%) of 6-[2-[4-(1H-indol-3-yl)-1-piperidinyl]ethyl]-3,7-dimethyl-5H-thiazolo[3,2-a]pyrimidin-5-one phosphate (2:3) monohydrate; mp. 214.4° C. (compound 28).
