348-40-3, 6-Fluorobenzo[d]thiazol-2-amine is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,348-40-3
Concentrated hydrochloric acid (0.067 mol) was added dropwise with stirring tohydrazine hydrate (0.12 mol) at 5-6 C followed by ethylene glycol (30 mL);thereafter, 6-uorobenzo[d]thiazol-2-amine (1) (20 mmol) was added in portionsand the resultant mixture was reuxed for 2-3 h and cooled at room temperature.The reaction progress was monitored by TLC using toluene:ethylacetate (75:25) asmobile phase. The reaction mixture was ltered and the resulting precipitates werewashed with distilled water. The resulting crude was recrystallized from ethanol. IR(KBr) mmax: 3010 (=C-H str), 1645 (C=C str), 1398 (C=N str). The 1HNMR(DMSO-d6) spectrum of this product showed signals: d 7.2-7.4 (3H, m, Ar C-H), at4.0 (1H, br, NH) and 4.75 (2H, br, NH2) ppm. The peaks in its 13CNMR (DMSO-d6)d: 106.1, 112.4, 115.5, 129.7, 145.5, 157.5, 171.2 ppm.
The synthetic route of 348-40-3 has been constantly updated, and we look forward to future research findings.
