Procedure

2,4,6-Trimethylphenol (0.114) was added to a solution of sodium methoxide (0.334 g) methanol (10 mL) and the resulting solution was evaporated to dryness under reduced pressure. The salt thus obtained was taken up in 10 mL of acetonitrile and added dropwise by to a cold solution (0-5° C.) of 7-chloro-3-(1-ethylpropyl)-5-methyl-3H-1,2,3-triazolo[4,5-d]pyrimidine in 35 mL of acetonitrile, such that the temperature did not rise above 5° C. The mixture was stirred at 0-5° C. for 3 hours. The solvent was then removed from the mixture under reduced pressure and the residue treated with water and extracted three times with methylene chloride. The combined extracts were dried over MgSO4 and stripped of the solvent under reduced pressure. The material was purified on silica gel using a solution of 1% methanol in methylene chloride to yield the title compound as a colorless powder, mp 92° C.
