40283-41-8, 2-Aminothiazole-4-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
2-Aminothiazole-4~carboxylic acid (1A) (0.5 g, 3.47 mmol) and 4-(3-Amino- pyhdin~4-yl)-piperazine-1-carboxylic acid tert-butyl ester (1B) (Ig5 3.59) were combined with anhydrous dmethylformamide (15 mL) and N, N-diisopropylethylamine (1 mL, 5.5 mmol), before adding N-[(dimethylamino)-1H-1 .2l3-triazolo[4.5-jb]pyridine- 1 -yImethyfene]-A/-methylmethanaminium Hexaffuorophosphate N-oxle (HATU) (2 g, (5.3 mmol). The reaction was stirred at room temperature for 16 hours, then stripped of solvent and stirred with a mixture (25:75 v/v) of 1 M aqueous KOH and saturated aqueous NaHCtheta3. The sticky brown residue was filtered, then rinsed with acetone to provide compound 1C (700 mg, 1.73 mmol, 50%) as an off-white solid. HPLC-MS tR ~ 1.076 min (UV 254). Mass calculated for formula C18H24N6O3S 404.49; observed IvIH+ (LCMS) 405.1 (m/z).
