Magnetically recoverable nano-magnetic catalyst supported with functionalized (n-propyl)-4-amino-pyridine silica (MNPs@SiO2-Pr-AP) was synthesized and characterized using different techniques. A simple and efficient synthesis of 2-amino-4-aryl thiazoles I [R = H, 4-Cl, 3-NO2, etc, X = CH, N] was described via condensation of acetophenones and thiourea using three different types of catalytic systems including N,N,N’,N’-tetrabromobenzene-1,3-disulfonamide [TBBDA], poly(N,N’-dibromo-N-ethylbenzene-1,3-disulfonamide) [PBBS] and a combination of TBBDA and MNPs@SiO2-Pr-AP. The results showed that, the use of TBBDA along with the MNPs@SiO2-Pr-AP gains the highest yields of the products in the shortest reaction time. In the experiment, the researchers used many compounds, for example, 4-(2-Amino-4-thiazolyl)phenol (cas: 57634-55-6Formula: C9H8N2OS).
4-(2-Amino-4-thiazolyl)phenol (cas: 57634-55-6) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Thiazole is a versatile building block for the construction and lead generation of new drug discoveries. Numerous diazole-based compounds are in clinical use as anticancer, antileukemic, antiinflammatory, antiviral, antifungal, antirheumatic, immunomodulator, and antiparasitic agents.Formula: C9H8N2OS
