42923-79-5, 7-Nitro-1,2,3,4-tetrahydroisoquinoline is a tetrahydroisoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step B; To a suspension of the product from Step A (12 g, 58 mmol), and pyridine (23.7 mL, 293 mmol) in anhydrous CH2Cl2 (50 ml) cooled at 0 C. was added in a dropwise manner trifluoroacetic anhydride (12 mL, 87 mmol), and the resulting mixture was stirred at room temperature for 18 h. The reaction mixture was poured onto ice (500 g) and extracted with CH2Cl2 (4¡Á150 mL). The combined CH2Cl2 layers were washed with 1 N HCl (4¡Á100 mL), saturated NaCl (100 mL), dried over Na2SO4, filtered and evaporated in vacuo to give the product (15.92 g, 89%); 1H NMR 500 MHz (CDCl3) delta=3.07 (2H, m), 3.91 and 3.94 (2H, t, J=6.2 Hz), 4.85 and 4.88 (2H, s), 7.36 (1H, dd, J=8.7 and 11.9 Hz), 8.07 (1H, dd, J=2.3 and 8.5 Hz), 8.01-8.08 (2H m).
As the paragraph descriping shows that 42923-79-5 is playing an increasingly important role.
