実験手順

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 1-(4-chloromethyl-thiazol-2-yl)-ethanone (1.08 g, 6.13 mmol) in dry DMF (21 mL) and treated with NaN3 (1.20 g, 18.39 mmol) at 65° C. until completion of the reaction. The reaction mixture was then cooled down to rt and partitioned between EA and water. The layers were separated and the org. layer dried over MgSO4, filtered and concentrated under reduced pressure to give crude 1-(4-(azidomethyl)-thiazol-2-yl)-ethanone as a yellow oil. To a solution of the crude azide (200 mg, 1.10 mmol) in THF (6 mL) were added polymer-supported Ph3P (2.0 eq.) and water (2 mL). The reaction mixture was stirred at 60° C. until completion of the reaction, cooled down to rt and filtered. The filtrate was partitioned between EA and aq. sat. NaHCO3 and the layers separated. The org. layer was dried over MgSO4, filtered and concentrated under reduced pressure to give the title compound as a brown oil after purification by FC (CH2Cl2-MeOH-Et3N). LC-MS-conditions 01: tR=0.26 min; [M+H]+=157.04.
