Procedure

Acetic anhydride (0.51 ml) was added directly to formic acid (2.0 ml) which had been cooled to 0° C. and then added a solution of 2-[4-[4-(5-chloropyridin-2-yl)piperazino]sulfonyl-3-(hydroxyamino)butyl]-5-fluoropyrimidine (0.485 g) in tetrahydrofuran (11 ml). The solution was stirred at room temperature for 3 hours and then evaporated in vacuo, the resulting residue was azeotroped with toluene and then it was dissolved in methanol and heated to 40° C. for 30 minutes. The solution was evaporated to dryness and then added diethylether and stirred at room temperature for 10 minutes, solid filtered, dried in vacuo to give N-[1-([4-(5-chloropyridin-2-yl)piperazino]sulfonylmethyl)-3-(5-fluoropyrimidin-2-yl)propyl]-N-hydroxyformamide, (0218 g), mp 154–155° C.
