Reaction Steps

N-[5-(3-Chloropropanesulfonylaminomethyl)-4-(2,2-dimethylpropionyl)-5-phenyl-4,5-dihydro-1,3,4-thiadiazol-2-yl]-2,2-dimethyl-propanamide (1.50 g, 2.90 mmol) obtained in Step 1 mentioned above, sodium iodide (8.69 g, 58.0 mmol) and sodium azide (1.89 g, 29.0 mmol) were suspended in DMF (20 mL), and the suspension was stirred at 90° C. for 4 hours. To the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was triturated with diethyl ether to give N-[5-(3-azidopropanesulfonylaminomethyl)-4-(2,2-dimethyl-propionyl)-5-phenyl-4,5-dihydro-1,3,4-thiadiazol-2-yl]-2,2-dimethyl-propanamide (1.82 g).
