Yield	Reaction Conditions	Operation in experiment
	With bromine; In 1,4-dioxane; at 20℃;	To a solution of <strong>[161957-59-1]1-(3-chloro-2-fluoro-phenyl)-ethanone</strong> (8.5 g, commercially available) in1 ,4-dioxane (50 ml.) Br2 (7.79 g) was added and the mixture was stirred at RT for overnight. Water was added to the mixture and the compound extracted with EA (30 ml. X 3). The organic phase was dried, filtered and the solvent evaporated under vacuum. The crude was purified by column to give the title compound (10.2 g).1H NMR (CDCI3) delta: 4.44 (2H, s), 7.15-7.20 (1 H, m), 7.62-7.66 (1 H, t), 7.79-7.85 (1 H, t).

(R,E)-N-(1-(3-chloro-2-fluorophenyl)ethylidene)-2-methylpropane-2-sulfinamide [ No CAS ]

Yield	Reaction Conditions	Operation in experiment
	With sodium hydrogencarbonate; In tetrahydrofuran; ethyl acetate;	Step 1: (R,E)-N-(1-(3-chloro-2-fluorophenyl)ethylidene)-2-methylpropane-2-sulfinamide (18a) To a solution of <strong>[161957-59-1]1-(3-chloro-2-fluorophenyl)ethanone</strong> (5.60 g, 31.5 mmol) and (R)-2-methylpropane-2-sulfinamide (5.72 g, 47.2 mmol) in THF (50.0 mL) was added tetraethoxytitanium (16.50 mL, 79 mmol) and the overall bright yellow solution was heated at 70 C. for overnight. The reaction was slightly cooled with ice-water bath, then was added EtOAc (50 mL), NaHCO3 (10 mL), and brine (10 mL). The slurry was filtered through a short path of Celite and the wet cake was washed with EtOAc. The resulted bright yellow solution was phase separated, and the organic layer was concentrated to afford the title compound (8.3 g, 30.1 mmol, 96% yield) as a light yellow oil. This material was used in the next step without purification. MS m/z=276.0 [M+H]+. Calculated for C12H15ClFNOS: 275.77.
