Pyrrolotriazines and related fused azaheterocycles have high potential for the synthesis of bioactive compounds, especially as a purine base isoster in carbon linked nucleosides. Although many structurally related compounds have already been synthesized and used in medicinal chemistry, pyrrolo[1,3,5]triazines have barely been described. The present work describes the synthesis of such heterocycles via condensation of 2-amino-3-ethoxycarbonylpyrrole with ethoxycarbonyliso(thio)cyanate. In a brief reactivity study of the obtained fused pyrroles, O- and S-alkylation, ester hydrolysis as well as regioselective bromination at the 6-position was demonstrated.

The invention provides a continuous preparation method for 2-aminopyrrolyl-3-ethyl carboxylate. The preparation method comprises the steps: continuously feeding a trichloroacetaldehyde solution to a first continuous reactor to carry out continuous acid catalyzed depolymerization on trichloroacetaldehyde, so as to a chloroacetaldehyde solution; and continuously feeding a 3-amino-3-imidoethyl propionate solution, an alkali solution and the chloroacetaldehyde solution to a second continuous reactor for a condensation reaction, thereby obtaining the 2-aminopyrrolyl-3-ethyl carboxylate. According to the continuous process, the restriction to anhydrous chloroacetaldehyde is broken through, the anhydrous chloroacetaldehyde is prepared by a continuous reaction, the reaction speed is higher than that of batches, and the yield is higher; and when the prepared chloroacetaldehyde solution is directly applied to the condensation reaction of next step, the material proportioning ratio is more controllable, the front and rear two steps can be compatible, and thus, the yield of the 2-aminopyrrolyl-3-ethyl carboxylate is globally increased. In addition, due to the continuous process, a scaling effect of the batches is avoided, and high yield during industrial application is also guaranteed.
