Electric Literature of 29026-74-2, The chemical industry reduces the impact on the environment during synthesis 29026-74-2, name is 2-Isopropoxyaniline, I believe this compound will play a more active role in future production and life.
EXAMPLE 4 Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (15 g) and 2-(1-methylethoxy)aniline (11.5 g) are added to ethanol (100 ml), and the mixture is refluxed with stirring for 17 hours. After cooling, the precipitate is collected by filtration and recrystallized from DMF to give ethyl 1,6-dihydro-2-[2-(1-methylethoxy)anilino]-6-oxo-5-pyrimidinecarboxylate (8.5 g). M.p. 205-207 C. Elemental analysis for C16 H19 N3 O4: Calcd. (%): C, 60.56; H, 6.03; N, 13.24. Found (%): C, 60.73; H, 6.12; N, 13.40. IR numaxnujol cm-1: 3000-3300 (NH), 1720 (C=O), 1600 (C=O). NMR (DMSO-d6) delta: 1.34 (6H, d, J=7 Hz, OCH(CH3)2), 1.30 (3H, t, J=7 Hz, OCH2 CH3), 4.26 (2H, q, J=7 Hz, OCH2 CH3), 4.73 (1H, m, OCH(CH3)2), 6.86-7.30 (3H, m, Ar–H), 8.32 (1H, d, J-8 Hz, Ar–H), 8.53 (1H, s, C4 –H), 8.20-12.30 (2H, b, 2*NH). Mass m/e: 317 (M+).
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, 2-Isopropoxyaniline, other downstream synthetic routes, hurry up and to see.
