Embodiment 1
[0048] A preparation method of thienopyrrole derivatives, which is prepared according to the following steps:
[0049] (1) Synthesis of 2-methyl azidocarboxylate:
[0050] Add sodium azide into the acetone / water solution of methyl chloroacetate under stirring at room temperature, then heat to 55-65°C for 4 hours, then place the reaction solution in a rotary evaporator, set the vacuum to -0.05--0.085MPa Rotary evaporation at a temperature of 45-55°C, the obtained residue was extracted with ethyl acetate, and then washed with an equal volume of saturated sodium bicarbonate solution and saturated saline solution respectively, after washing, anhydrous sodium sulfate was added to dry for 13 hours, filtered and dried After concentration, light yellow oily methyl 2-azidocarboxylate is obtained; the mol ratio of sodium azide to methyl chloroacetate is 2:1, and the mass volume ratio of sodium azide to methyl chloroacetate in acetone / water solution is 13: 200, the volume ratio of aceto...
Embodiment 2
[0063] A preparation method of thienopyrrole derivatives, which is prepared according to the following steps:
[0064] (1) Synthesis of 2-methyl azidocarboxylate:
