I (R = R1 = Cl, F; R = Cl, R1 = F) and II (R2, R3 = Me, CF3) were prepd. by the addn. of N-aminophthalimide, or the corresponding aminopyrrolidones to the isocyanates III. .

GB 2134518 A1 15 Aug 1984, 11 pp.Chemical with cas number 1897-52-5 also plays role. (English). (United Kingdom). CODEN: BAXXDU. CLASS: IC: C07D207-327. APPLICATION: GB 84-2936 3 Feb 1984. PRIORITY: CH 83-726 9 Feb 1983. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5 Ureas I (R, R2, R3 = H, halo; R1 = H, halo, Me) were prepd. Thus 2,6-dichloro-4-nitroaniline was treated with 3,5-dimethoxytetrahydrofuran to give 3,5-dichloro-4-pyrrolonitrobenzene which was reduced to the aniline and treated with 2,6-F2C6H3CONCO to give II. 2,6-F2C6H3CONCO was prepd. by hydrolyzing 2,6-F2C6H3CN and treating 2,6-F2C6H3CONH2 with ClCOCOCl. At 10 ppm II gave 100% mortality of Lucilia sericata larvae. .
