실험 절차

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of this crude mixture of 2-(5-acetyl-thiophen-2-ylmethyl)-oxazole-4-carbonyl chloride and 2-[5-(2-methyl-[1,3]dioxolan-2-yl)-thiophen-2-ylmethyl]-oxazole-4-carbonyl chloride in dry acetone (12.0 mL) was cooled to 0° C. and a solution of sodium azide (262 mg, 3.98 mmol) in H2O (1.4 mL) was added over 1 h. The reaction mixture was stirred at 0° C. for 45 min. The mixture was concentrated under reduced pressure (co-evaporation with toluene) then dissolved in CH2Cl2 and filtered. The filtrated was concentrated under reduced pressure to give the title compound (LC-MS-conditions 01: tR=0.85 min, [M+H]+=276.91) along with 2-[5-(2-methyl-[1,3]dioxolan-2-yl)-thiophen-2-ylmethyl]-oxazole-4-carbonyl azide (LC-MS-conditions 01: tR=0.91 min, [M+H]+=320.92) as a brown solid.
