Methane → HCID 13364715, compound

Participants

Reaction Steps

To a solution of 2-aminotriazole (2.1 g) in 100 ml of methylene chloride was added 10 ml of a 2M solution in toluene of trimethylaluminum (1.44 g of Al(CH3)3) by syringe. Evolution of methane gas was seen and the solution became homogeneous. To this mixture was added 4.0 g of N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide and the homogeneous solution was heated at reflux for 18 hours. The reaction mixture was then heated with aqueous hydrochloric acid and the precipitated product isolated by filtration, 1.42 g, m.p. 185°-187° C. IR: 1690 cm-1 and 1700 cm-1 unresolved double carbonyl, NMR: in TFA 2.7 ppm s, CH3 pyrimidine, 4.2 ppm s, OCH3 on pyrimidine, 6.7 ppm s, proton in 5-position on pyrimidine, 7.8-8.0 ppm and 8.4-8.5 ppm M, aromatic, 7.6, 7.7 ppm D, thiazole.
