Методика

8-Benzyloxy-5-((R)-2-bromo-1-hyroxyethyl)-1H-quinolin-2-one (20.8 g, 55.6 mmol) and sodium azide (3.61 g, 55.5 mmol) were suspended in N,N-dimethylformamide (100 mL) and the mixture was stirred at 65° C. for 3 hours. Sodium azide (1.81 g, 27.8 mmol) was added thereto and the mixture was stirred at the same temperature overnight. To the reaction solution was added purified water and stirred at room temperature for 1 hour. The precipitate was collected by filtration and washed with purified water. By drying under reduced pressure, 5-((R)-2-azido-1-hyroxyethyl)-8-benzyloxy-1H-quinolin-2-one (16.8 g) was obtained.
