Reaction Steps

A mixture of 1,3-dipropyl-8-(1H-pyrazol-4-yl)-7-(2-trimethylsilanyl-ethoxymethyl)-3,7-dihydro-purine-2,6-dione (0.100 g, 0.23 mmol), methanesulfonic acid 2-oxo-1-(3-trifluoromethyl-phenyl)-pyrrolidin-3-ylmethyl ester (0.10 g, 0.32 mmol), K2CO3 (0.045 g, 0.32 mmol) and DMF (1 ml) was heated at 75-80° C. for 16 hrs. Reaction mixture was cooled to 20-25° C. and diluted with water (10 ml). The aqueous layer was extracted with ethyl acetate, washed with saturated brine solution. The organic layer was dried over Na2SO4 and evaporated to obtain crude product (0.2 g). The crude product was purified by preparative TLC to obtain pure 8-{1-[2-oxo-1-(3-trifluoromethyl-phenyl)-pyrrolidin-3-ylmethyl]-1H-pyrazol-4-yl}-1,3-dipropyl-7-(2-trimethylsilanyl-ethoxymethyl)-3,7-dihydro-purine-2,6-dione (0.10 g, 65%).
