Chloroform → 4-[6-Amino-8-(3-fluorophenyl)-2-iodo-9H-9-purinyl]butanoic Acid

Participants

Reaction Steps

To 1.50 g of 4-[6-amino-8-(3-fluorophenyl)-2-iodo-9H-9-purinyl]butanol were added 30 ml of chloroform, 30 ml of acetonitrile, 45 ml of water, 73 mg of ruthenium tetraoxide hydrate and4.10 g of sodium periodate and the mixture was vigorously stirred in a nitrogen stream for 5 hours at room temperature. The reaction was stopped by 2-propanol and the insoluble matters were filtered off followed by washing with 1000 ml of chloroform-methanol (1:1). The filtrate was concentrated, the residue was suspended in water, and the suspension was adjusted to pH 2-3 with 1N hydrochloric acid and the crystals were collected by filtration. The crystals were washed with water and ether to give 1.41 g of the title compound. The yield was 91%.
