Related Products of 153435-63-3, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.153435-63-3, name is 2-(Tributylstannyl)pyrimidine, molecular formula is C16H30N2Sn, molecular weight is 369.1328, as common compound, the synthetic route is as follows.
3-(6,7-Dimethoxy-quinolin-4-yloxy)-quinolin-2-ol (50 mg), diphosphorus pentaoxide (51 mg), and tetrabutylammonium bromide (69 mg) were suspended in 1,2-dichlorobenzene (1 ml), and the suspension was stirred at 140C for 1.5 hr. The reaction mixture was cooled to room temperature, and a 10% aqueous sodium hydrogencarbonate solution was added thereto. The mixture was extracted with chloroform, and the chloroform layer was washed with water and saturated brine and was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography with a chloroform-methanol system to give 4-(2-bromo-quinolin-3-yloxy)-6,7-dimethoxy-quinoline (5 mg, yield 8%). 4-(2-Bromo-quinolin-3-yloxy)-6,7-dimethoxy-quinoline (50 mg), tetrakistriphenylphosphine palladium (0) (28 mg), and copper(II) oxide (19 mg) were suspended in N,N-dimethylformamide (1.5 ml). 2-Tributylstannylpyrimidine (90 mg) was added to the suspension, and the mixture was stirred at 100C overnight. The reaction mixture was cooled to room temperature and was then filtered. The solvent was removed from the filtrate by distillation under the reduced pressure. Water was added thereto, and the mixture was extracted with dichloromethane. The dichloromethane layer was washed with water and saturated brine and was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography with a chloroform-methanol system to give the title compound (28 mg, yield 56%). 1H-NMP, (CDCl3, 400 MHz): delta 4.05 (s, 6H), 6.44 (d, J = 5.2 Hz, 1H), 7.43 – 7.78 (m, 8H), 7.88 (s, 1H), 8.11 (d, J = 8.4 Hz, 1H), 8.52 (d, J = 5.2 Hz, 1H) Mass spectrometric value (ESI-MS, m/z): 411 (M++1)
Statistics shows that 153435-63-3 is playing an increasingly important role. we look forward to future research findings about 2-(Tributylstannyl)pyrimidine.
