A new synthetic strategy for the synthesis of novel 3-(3-(3-methyl-4- nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl-7H-thiazolo[3,2-a]pyrimidin-3-yl) propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines (7a-i) analogues is described. Reaction of 3-(2-(3-methyl-4-nitroisoxazole-5-yl)-1-phenylethyl)pentane-2,4- dione (3) with two moles of thiourea in presence of iodine and CuO afforded 4-(1-(2-aminothiazol-4-yl)-3-(3-methyl-4-nitroisoxazol-5-yl)-2-aryl propyl-thiazol-2-amine (5). Compound 5 on reaction with two moles of chalcone (6) furnished novel 3-(3-(3-methyl-4-nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl- 7H-thiazolo[3,2-a]pyrimidin-3-yl)propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines (7a-i).
