Procedure
91.5 mg of morpholine and 207 mg of potassium carbonate were added to a solution of 169 mg of the mixture of 5-bromomethyl-2-furan-2-yl-7-propoxy-oxazolo[5,4-d]pyrimidine and 2-(5-bromo-furan-2-yl)-5-bromomethyl-7-propoxy-oxazolo[5,4-d]pyrimidine obtained in step (a) in 3 ml of dimethylformamide. The reaction mixture was stirred at room temperature for 48 h. Then 50 ml each of water and ethyl acetate were added, the mixture was filtered through a Varian ChemElut cartridge, the cartridge washed with 10 ml of ethyl acetate, and the combined filtrates were evaporated to dryness in vacuo. Preparative HPLC (method HPLC1) of the residue yielded 41 mg of 2-(5-bromo-furan-2-yl)-5-morpholin-4-ylmethyl-7-propoxy-oxazolo[5,4-d]pyrimidine (example 3) and 25 mg of the title compound in the form of 2-furan-2-yl-5-morpholin-4-ylmethyl-7-propoxy-oxazolo[5,4-d]pyrimidine trifluoroacetic acid salt.
