Procedure

To a solution of N-[(1S,2R,3S,4R)-4-(2,6-dichloro-purin-9-yl)-2,3-dihydroxy-cyclopentyl]-propionamide (Intermediate J7) (2.6 g, 7.22 mmol) in dry THF (26 ml) is added C,C-Bis-(4-methoxy-phenyl)-methylamine (Intermediate Y) (3.5 g, 14.44 mmol). The mixture is heated at 50° C. for 12 hours and then concentrated in vacuo. The residue is dissolved in chloroform and washed sequentially with 1.5N HCl, water and saturated aqueous brine solution. The organic phase is dried over anhydrous sodium sulphate and concentrated in vacuo. The crude product is purified by chromatography on silica (60-120 mesh) eluting with 2% methanol in chloroform to afford the title product. LC-MS (0.1% formic acid, acetonitrile): (MH+ 567)
