Reaction Steps

Next, the resulting optically active N-[5-(3-azidopropanesulfonylamino-methyl)-4-(2,2-dimethylpropionyl)-5-phenyl-4,5-dihydro-1,3,4-thiadiazol-2-yl]-2,2-dimethylpropanamide was dissolved in THF (53 mL), and water (10.6 mL) and triphenylphosphine (1.24 g, 4.73 mmol) were added, then the mixture was stirred at room temperature for 16 hours. The mixture was concentrated under reduced pressure, and water and saturated aqueous sodium hydrogencarbonate were added, then the mixture was extracted with ethyl acetate. The organic layer was extracted with aqueous hydrochloric acid, and the aqueous layer was made basic by adding saturated aqueous sodium hydrogencarbonate, and then extracted with ethyl acetate. The resulting organic layer was concentrated under reduced pressure to give Compound w {N-[5-(3-aminopropanesulfonylaminomethyl)-4-(2,2-dimethylpropionyl)-5-phenyl-4,5-dihydro-1,3,4-thiadiazol-2-yl]-2,2-dimethylpropanamide} (1.29 g, 89%).
