Procedure

To NaH (2.4 mmol, 115 mg, 50% in oil, pentane washed and decanted), in DMF (5 mL) was added 2-methyl-6-mercaptopurine (400 mg, 2.4 mmol) in portions, at 0° After stirring 2 h 1-(1-chloro-2-hydroxy-3-propanyl)-4-(4,4'- difluorobenzhydryl)piperazine (2.4 mmol, 0.914 g) was added in DMF (5 mL) dropwise over 15 min, at 0° C., under nitrogen. After three days, the solution was filtered and the DMF removed from the filtrate in vacuo (vacuum oven, 1 mm Hg, 60° C.) to give the crude product. Silica gel flash column chromatography using 10% MeOH:CH2Cl2 gave the product with DMF. This product was dried 72 h in vacuo (room temperature, 1 mm Hg) to give pure product (290 mg, 23.2%). mp 83°-86° C. (dec.) DCI/MS (M+1)=511. (300 MHz) 1H NMR (CDCl3)δ: 8.1 (s, 1H), 7.3 (m, 4H), 6.95 (m, 4H), 4.2 (s, 1H), 4.15 (m, 1H), 3.4 and 3.6 (d of d, 2H), 2.65 (s, 3H), 2.6 (M, 6H), 2.4 (m, 4H).
