YieldReaction ConditionsOperation in experiment
29% In ethanol; at 80℃; for 2.0h; The compound IN-1 (540 mg, 2.67 mmol) and thiourea (244 mg, 3.21 mmol) in ethanol (10 mL) were heated to 80 C for 2 hours.After the reaction mixture was cooled to room temperature, the ethanol was spun off.Add 20 mL of water and stir for 10 minutes, filter, filter cake twice with water, and finally spin the filter cake to give 4-(5-methylfuran-2-yl)thiazole-2-amine (140 mg,Yield 29%, white solid).
1 eq of substituted 2-bromoacetone, 1 eq of thiourea then 2 ml of EtOH are introduced into a 2-5 mL tube suitable for microwaves (Personal Chemistry). The solution is pre-stirred for 15 s in the apparatus at room temperature and is then heated for 4 min at 170 C. The progress of the reaction is evaluated by TLC and LC-MS. After hydrolysis by H2O and NaHCO3 (to pH = 9-10), the aqueous phase is extracted with AcOEt. The organic phases are washed with a saturated NaCl solution, dried over MgSO4, filtered and concentrated. Analysis of the crude product (1H NMR, LC-MS) shows that purification is unnecessary. The substituted amino-thiazoles obtained are used directly in urea synthesis reactions.; 4-(5-methyl-furan-2-yl)-thiazoI-2-yl-amine (Method 4)Method 4 above was used to prepare the aforementioned product.1H NMR (400 MHz, CDCl3): δ 6.62 (s, IH, HtM220,.), 6.51 (d, IH, Hfuran), 6.03 (d, IH, Hfuran),5.20-5.08 (m, 2H, NH2), 2.36 (s, 3H, CH3)MS: 181.06 (M+H)+Rf: 0.20 (silica, heptane/AcOEt 1/1)
