Synthetic Route of 92525-10-5, The chemical industry reduces the impact on the environment during synthesis 92525-10-5, name is 3-Iodo-1-methyl-1H-pyrazole, I believe this compound will play a more active role in future production and life.
A mixture of 5-((1,2,3,5,6,7-hexahydro-s-indacen-4-yl)amino)-1-((2-(trimethylsilyl)- ethoxy)methyl)-1H-1,2,4-triazole-3-thiol (Intermediate B9) (230 mg, 417.01 mumol, 1 eq), 3-iodo-1-methyl-1H-pyrazole (86 mg, 417.01 mumol, 1 eq), CuI (158 mg, 834.02 mumol, 2 eq) and N,N’-dimethylethane-1,2-diamine (735 mg, 8.34 mmol, 20 eq) in dioxane (4 mL) was stirred at 70C under N2atmosphere for 2 hours. The reaction mixture was poured into water (10 mL) and extracted with EtOAc (3 × 10 mL). The organic layers were dried over anhydrous Na2SO4, filtered and concentrated in vacuum. The residue was purified by prep-TLC (SiO2, petroleum ether: ethyl acetate, 1:1) to give the title compound (170 mg, 82.7% yield, 98% purity on LCMS) as a yellow solid.1H NMR (400 MHz, CDCl3): d 7.34 (d, 1H), 6.94 (s, 1H), 6.47 (d, 1H), 6.18 (s, 1H), 5.31 (s, 2H), 3.90 (s, 3H), 3.61 (t, 2H), 2.87 (t, 4H), 2.69 (t, 4H), 2.09-2.00 (m, 4H), 1.00- 0.88 (m, 2H), 0.02 (s, 9H).LCMS: m/z 483.2 (M+H)+(ES+).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Iodo-1-methyl-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
