Yield	Reaction Conditions	Operation in experiment
83%	With aluminum (III) chloride at 135℃; for 1h;	20 General procedure: To a flask containing 2,3-dimethylphenyl acetate (1.85 g, 1 1.27 mmol, 1.0 eq.), AlC (1.73 g, 16.90 mmol, 1.5 eq.) was added portionwise. The reaction was continued at 135°C for 1 h. The resulting solid was then hydrolyzed with a mixture of ice and diluted HCI aqueous solution and extracted with AcOEt three times. Organic layers were combined, washed with diluted NaOH aqueous solution, dried, filtered off and concentrated in vacuo. The oily residue was purified by FCC (SiHP, Hexane: AcOEt 4:1) to afford the title compound (1.40 g, 8.53 mmol, yield 76%) as a white solid.

100%	With potassium carbonate In acetonitrile at 76℃; for 48h;	1.1a Example 1: Synthesis of the monohydrate potassium salt of formula (I) la) Synthesis of l-(5-benzyloxytetralin-6-yl)ethanone ( 1 ) 6-Acetyl-5-hydroxytetralin (100 g, 1 eq.) was dissolved in acetonitrile (300 mL). After addition of K2CO3 (1.1 eq.) and benzyl bromide (1.05 eq.), the suspension was heated (76°C). After 48 hours, benzyl bromide (0.1 eq) was added. After overall 74 hours, the solid was filtered off and washed with acetonitrile (200 mL), and the combined filtrates were evaporated. (0168) Compound 1 was obtained as a syrup: m = 148.6 g, quantitative yield, 96.6% a/a purity.
