Quinazolines. Noda, Kanji; Nakagawa, Akira; Hachiya, Terumi; Ide, Hiroyuki (Hisamitsu Pharmaceutical Co., Ltd., Japan). Japan. Kokai JP 52071484 14 Jun 1977 Showa, 3 pp.In this experiment, several chemicals are used like 56739-41-4 (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07D239-95. APPLICATION: JP 75-148303 11 Dec 1975. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Seven quinazolinones I (R = Me, Et, iso-Pr, cyclopropylmethyl, CH2CF3; x = m, p), having analgesic, antiinflammatory, and central depressant activity (no data), were prepd. by reaction of II with CSX2 (X = Cl, imidazolyl). Thus, 2.7 g II (R = Me, x = m) in THF and 1.0 g ca. 50% NaH were stirred 30 min at room temp., 3.5 g CSCl2 was added, and the mixt. stirred 1 h at room temp. to give 2.2 g I (R = Me, x = m). .
