Yield	Reaction Conditions	Operation in experiment
	With bromine; In water; acetic acid;	PREPARATION I 2-bromo-1-(2,4,6-trimethylphenyl)-1-ethanone (Compound 1) Dissolve 0.3 mol of 1-(2,4,6-trimethylphenyl)-1-ethanone in 200 ml of glacial acetic acid, and add 31.8 g of bromine dropwise while maintaining the reaction medium at a temperature below 10 C. When the addition is complete, allow the reaction medium to return to room temperature and leave at this temperature for 2 hours. Then pour the reaction medium into 500 ml of ice-cold water and extract the aqueous phase with ethyl ether. Wash the organic extracts with saturated aqueous sodium bicarbonate solution and then with salt water, and dry over anhydrous magnesium sulphate. After evaporation of the solvent, an oil is obtained, which may be used without further purification.
	With copper(ll) bromide; In ethyl acetate; for 1.5h;Reflux;	Synthesis of Exemplary Aminothiazoles and the Related Intermediates2-Bromo-1-mesitylethanone. To a solution of 1-mesitylethanone (1.02 g, 6.27 mmol) in EtOAc (50 mL) was added copper(II) bromide (CuBr2, 2.85 g, 12.8 mmol). The reaction mixture was heated at reflux for 90 min. The solution was allowed to cool down, and the resultant solids were filtered off and washed with EtOAc. The filtrate was concentrated under reduced pressure to give crude 2-bromo-1-mesitylethanone (1.67 g) as yellow oil: 1H NMR (500 MHz, CDCl3) delta 6.87 (2H, s), 4.27 (2 H, s), 2.31 (3H, s), 2.22 (6H, s).

Yield	Reaction Conditions	Operation in experiment
	With aluminum (III) chloride; In dichloromethane; at 0 - 5℃;	General procedure: (ii)To a stirred solution ofAlCl3 (12 mmol, 3.0 equiv.) in dichloromethane(10 mL) was added 8m or 8n(4 mmol, 1.0 equiv.) at 0 . Then a solution of2-bromoacetyl bromide (8 mmol, 2.0 equiv.) in dichloromethane (5 mL) was added dropwisein a period of 10 min. The reaction mixture was stirred at 0~5 for additional 15~30 min. After that, carefully added theNaHCO3 until pH > 7 and extracted with dichloromethane (3*15mL).The combined organic layers were dried over anhydrous Na2SO4and concentrated in vacuo to affordcrude product 2-bromo-1-arylethanone 9m or 9n as yellow solid, which directly using for next step.
