Procedure

To 6-[1-[1-[bis(4-fluorophenyl)methyl]homopiperazin-4-yl]-2-hydroxy-3-propanylthio]purine (0.26 g, 0.51 mmol) (the filtrate from above) in methylene chloride (2 mL) was added acetic anhydride (0.05 mL, 0.51 mmol) in Et3N (0.07 mL, 0.51 mmol) at room temperature under a nitrogen atmosphere. After three days, the solution was filtered and the filtrate extracted with aqueous saturated sodium bicarbonate (2×50 mL), water (1×50 mL) and saturated brine (1×50 mL), and dried over Na2SO4. Evaporation of the solvent gave a white solid (390 mg). After several washings with pentane, the solid was dried in a vacuum oven for 4 days to give pure product (0.160 g, 56.8%) as a white solid, mp 88°-90° C. (dec). DCI/MS (M+1) 553; 300 MHZ1H NMR (CDCl3) δ: 8.7 (s, 1H), 8.1 (s, 1H), 7.3 (m, 4H), 6.95 (m, 4H), 5.3 (m, 1H), 4.1 and 3.45 (q of q, 2H), 2.6-2.8 (m, 10H), 2.0 (s, 3H), 1.75 (m, 2H).
