YieldReaction ConditionsOperation in experiment
55.0% In ethanol; at 20℃; for 48h; A solution of ethyl 3-bromopyruvate (1.95 g, 10 mmol, 1.0 eq) and 2, 2, 2-trimethyl-thioacetamide (1.17 g, 10 mmol, 1.0 eq) in 20 mL of ethanol was stirred at room temperature for 48 h. The solvent was evaporated under reduced pressure, and the residue was extracted with aqueous sodium bicarbonate and DCM. The DCM layer was dried over anhydrous magnesium sulfate and evaporated to dryness. The residue was separated by column chromatography to give 2-tert-butyl-thiazole-5-carboxylic acid ethyl ester as a colorless oil (1.15 g, 55.0% yield). 1H NMR (400 MHz, CDCl3) delta 8.01 (s, 1H), 4.38 (q, J=7.1 Hz, 2H), 1.46 (s, 9H), 1.37 (t, J=7.1 Hz, 3H).

YieldReaction ConditionsOperation in experiment
55% With lithium hydroxide monohydrate In tetrahydrofuran at 20℃; for 16h; 16.2 Preparation of 2-tert-butyl-thiazole-5-carboxylic acid To a 2-tert-butyl-thiazole-5-carboxylate in 10 mL of THF, 5 mL of lithium hydroxide (0.45 g, 10.9 mmol, 1.1 eq) aqueous solution was added and the obtained solution was stirred at room temperature for about 16 h. The solvent was evaporated under reduced pressure, and the residue was dissolved in 5 mL of water. The pH was adjusted to about 3 with 2M HCl, and a large amount of white flocculent solid was precipitated. The filter cake was washed with water (2×5 mL) to give 2-Tert-butyl-thiazole-5-carboxylic acid as a white solid (0.55 g, 55.0% yield). MS m/z (ESI): 184.0 [M-H].
With ethanol; lithium hydroxide monohydrate; sodium hydroxide at 20℃; for 5h; 180 Ethyl 2-tert-butylthiazole-5-carboxylate (350 mg, 1.64 mmol, 1 eq) in methanol (1 mL) was saponified under standard conditions using added sodium hydroxide (6 M, 1 mL, 3.66 eq) to provide the carboxylic acid intermediate (150 mg, crude) as a white solid.

The mixture was stirred at 110 °C for 12 h. The residue was poured into ice-water (w/w = 1/1) (100 mL). The aqueous phase was extracted with EA (20 mLx3). The combined organic phase was washed with brine (20 mLx3), dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by prep-TLC (SiO2, PE: EA=5:1) to afford the thaizole product (350 mg, 64.1% yield) as a light yellow oil.
