With triethylamine; In ethanol; at 150℃; for 2h; | Step 1: A solution of <strong>[4175-78-4]2,5-dibromothiazole</strong> (1.0 equiv.), morpholine (1.5 equiv.) and triethylamine (4 equiv.) were heated to 150 C. for 2 h in the microwave. After concentration, the mixture was partitioned between water and EtOAc. The organic phase was washed with brine and dried over sodium sulfate. The solution was concentrated and dried under vacuo to give crude N-(4-methyl-3-(2-morpholinothiazol-5-yl)phenyl)-3-(trifluoromethyl)benzamide and was used in the next step without further purification.

The reaction mixture was heated in the microwave reactor to 100° C. for 45 min. The reaction mixture was partitioned between CHCl3 and H2O, and the layers were separated. The aqueous layer was re-extracted with CHCl3 (3 ×) and the combined organic fractions were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude material was purified by chromatography on silica gel [eluting with 1.5% MeOH in CHCl3] resulting in a yellow solid slightly contaminated with triphenylphosphine oxide. Therefore, this material was dissolved in MeOH/THF and passed through a prewashed 5 g SCX column. The column was washed with 2 volumes of MeOH and 2 volumes of THF then was washed with 1M NH4OH in MeOH upon which the product was released from the resin. The filtrate was concentrated in vacuo, and the resulting material was chromatographed on silica gel [eluting with 0.5% MeOH in CHCl3] resulting in the title compound as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ=3.37-3.49 (m, 4H), 3.68-3.81 (m, 4H), 7.05 (s, 2H), 7.51-7.62 (m, 2H), 8.03 (dd, J=8.4, 4.8 Hz, 1H), 8.07 (d, J=2.2 Hz, 1H), 8.23 (d, J=2.2 Hz, 1H), 8.36 (s, 1H), 9.64 (s, 1H).
