The screening of a small library of diverse chemical structures resulted in the identification of 2-thioxodihydropyrido[2,3-d]pyrimidine 10a as having broad spectrum antibacterial activity (MIC 0.49-3.9 μg mL-1), and reasonable antifungal activity (MIC 31.25 μg mL-1). An expeditious synthesis of 10a was optimized by varying solvents, catalysts and the use of microwave irradiation with the best conditions using DMF as a solvent, I2 (10 mol%) and a 30 minutes reaction time compared to 15 h for classic conventional heating. The pharmacokinetic properties and calculation of drug likeness of 10a suggested good traditional drug-like properties and led to the synthesis of a small library with seven compounds 10a and 10d-i showing broad antimicrobial activity (MIC = 0.49-7.81 μg mL-1) and selectivity indices of more than 5.6 against the normal colon cell line (CCD-33Co). The antifungal activity of compounds 10d-i was moderate to strong with MIC values of 1.95-15.63 μg mL-1.

Paragraph 0108-0110, (2021/10/27)
The production process of 4 - chloropyrrolo [2, 3 - d] pyrimidine comprises the following steps: S1, adding the compound I and the compound II to the mixed solvent I, carrying out temperature rise reaction under the catalysis of the base I to obtain the compound III. S2, sodium alkoxide I was added to alcoholic solvent II, compound IV and compound III were added to raise the temperature, and organic solvent III, organic solvent IV and compound V were added to raise the temperature to give 4 - chloropyrrolo [2, 3 - d] pyrimidine crude product. Among them, compound I is. . Compound II was obtained. . Compound III was obtained. . The compound IV is formamidine. Compound V was POCl. 3 To the method, bromoacetaldehyde dimethyl acetal and cyanoethyl acetate are subjected to reflux reaction, and 2 - cyano -4, 4 - methoxybutyric acid ethyl ester and formamidine acetate are subjected to one-pot chlorofluorination reaction, so that the reaction period is greatly shortened.
