ETHYL 4-CHLORO-2-QUINAZOLINECARBOXYLATE Chemical Properties,Usage,Production

Uses

Ethyl 4-Chloroquinazoline-2-carboxylate is a reactant used in the synthesis and evaluation of novel quinazoline-based anti-inflammatory agents acting as PDE4B inhibitors.

Synthesis

29113-33-5

34632-69-4

General procedure for the synthesis of ethyl 4-chloroquinazoline-2-carboxylate from ethyl 4-quinazolinone-2-carboxylate: To a suspension of ethyl 4-quinazolinone-2-carboxylate (1.2 g, 5.5 mmol) in chloroform (20 mL) was added sequentially N,N-dimethylformamide (6 drops) and thionyl chloride (4.8 mL, 66 mmol). The reaction mixture was heated to reflux for 4.5 hours. After completion of the reaction, it was cooled to room temperature and concentrated under reduced pressure to remove the solvent. Ice water was added to the residue and a white solid precipitated. The solid product was collected by filtration, washed with cold water and dried to afford ethyl 4-chloroquinazoline-2-carboxylate (1.26 g, 97% yield). The product was confirmed by 1H NMR (400 MHz, CDCl3): δ 8.38 (dd, J = 0.74 Hz, 8.34 Hz, 1H), 8.31 (d, J = 8.48 Hz, 1H), 8.07 (m, 1H), 7.87 (m, 1H), 4.61 (q, J = 7.12 Hz, 2H), 1.50 (t, J = 7.14 Hz, 3H).IR spectra (diamond cell, cm-1 ) showed characteristic absorption peaks: νmax 1731.3, 1549.8, 1479.8, 1338.4, 1179.4, 913.0, 764.3, 693.9.Melting point is 86-88 °C.
