Yield	Reaction Conditions	Operation in experiment
91.4%		A solution of DCM (30 ML) was cooled TO-78C and oxalyl chloride (1.34 ml, 15. 2MMOL, 1.2eq) was added under nitrogen followed by dropwise addition of DMSO (2.2 ml, 31.7mmol, 2. 5EQ) in DCM (10ml). After stirring for 15 min a solution of 2- chloro-3-methylbenzylalcohol (2g, 12.7mmol, leq) in DCM (12 ml) was added dropwise. After a further 30 min triethylamine (9.03 ml, 63. 5MMOL, 5EQ) was added in one portion and the mixture warmed to room temperature over 1 hour. The reaction mixture was quenched with saturated aqueous sodium hydrogen carbonate (50 ml) and the aqueous layer extracted with DCM (2 x 50 ml). The combined organic extracts were dried (MGS04) and the solvent removed in vacuo to give 2-chloro-3-methylbenzaldehyde (1.8g, 91.4%) as a yellow oil; 1H NMR (300 MHz, CDC13) 8= 10. 53 (1H, s, CHO), 7.81- 7.74 (1H, m, ArH), 7.53-7. 46 (1H, m, ArH), 7.34-7. 23 (1H, m, ArH) and 2.46 (3H, s).
	With manganese(IV) oxide; In dichloromethane; at 25℃; for 12h;Inert atmosphere;	To a solution of (2-chloro-3-methyl-phenyl)methanol (26.2 g, 167 mmol) in dichloromethane (350 mL) was added manganese dioxide (116 g, 1.34 mol) under nitrogen. After the addition, the reaction mixture was stirred at 25 C for 12 hrs. The solid was filtered, and the filtrate was concentrated under vacuum. The residue was purified by column chromatography (eluted with petroleum ether:ethyl acetate = 20:1) to give the title compound.1H NMR (400MHz, DMSO-d6) delta = 10.42 - 10.34 (m, 1H), 7.68 (t, J = 8.2 Hz, 2H), 7.42 (t, J = 7.5 Hz, 1H), 2.39 (s, 3H)

To a solution of (2-chloro-3-methyl-phenyl)methanol (26.2 g, 167 mmol) in dichloromethane (350 mL) was added manganese dioxide (116 g, 1.34 mol) under nitrogen. After, the reaction mixture was stirred at rt for 12 hrs. The solid was filtered, and the filtrate was concentrated under vacuum. The residue was purified by column chromatography (eluted with petroleum ethenethyl acetate = 20: 1) to give the title compound.
