A mixture comprising N-{(1S,2R,3S,4R)-4-[2-((R)-3-amino-pyrrolidin-1-yl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-propionamide (Example 18 step 2) (30 mg, 0.053 mmol) and 4,5-dihydro-1H-imidazole-2-thiol hydroiodide (24 mg, 0.106 mmol) in absolute ethanol (2 ml) is treated with DMAP (catalytic amount) and TEA (29 μl, 0.212 mmol). The resulting mixture is heated using microwave radiation in a Personal Chemistry Emrys™ Optimizer microwave reactor at 150° C. for 4000 s. The solvent is removed in vacuo and purification of the crude product by preparative HPLC ((30-95% acetonitrile in water—0.1% TFA) affords the title compound. (MH+ 639.63)
