YieldReaction ConditionsOperation in experiment
35% 4-Chloro-6-iodo-quinazoline (1.00 g; 3.44 mmol) and 0.70 g (4.64 mmol) of thiazolo[5,4-b]pyridin-2-yl-amine were heated at 135C for 4 hours with stirring in 10 ml of phenol. Chloroform was added to the reaction solution followed by washing with a 1N aqueous solution of sodium hydroxide. The organic layer was dried and concentrated and the resulting residue was purified by a silica gel column chromatography (chloroform : methanol = 50:1) to give 486 mg (yield: 35%) of (6-iodo-qunazolin-4-yl)-thiazolo[5,4-b]pyridin-2-yl-amine as a yellow solid. To a solution of 80 mg (0.197 mmol) of the resulting iodine compound in 2 ml of N,N-dimethylacetamide were added 38 mg (0.197 mmol) of copper iodide, 128 mg (0.394 mmol) of cesium carbonate and 30 mg (0.295 mmol) of 3-mercapto-1,2,4-triazole followed by stirring at 140C for 5 hours. Water was added to the reaction solution followed by extracting with chloroform. The organic layer was dried and concentrated and the resulting residue was purified by a thin layer silica gel chromatography (chloroform : methanol = 8:1) to give 15 mg (yield: 20%) of the title compound as a yellow solid. 1 HNMR(CDCl3) δ: 7.43-7.46(1H,m),7.82(1H,d,J = 8.8Hz),7.90(1H,d,J = 8.8Hz),8.05(1H,d,J = 8.0Hz),8.18(1H,s),8.31(1H,s),8.43(1H,d,J = 3.6Hz),8.69(1H,s) ESI-MS(m/e):379[M+H]+
