実験手順: To a solution of (2-chloro-4-methylphenyl)methanol (365 mg, 2.331 mmol) and Et3N (0.390 mL, 2.80 mmol) in Dichloromethane (DCM) (10 mL) at 0° C. AcOCl (0.331 mL, 4.66 mmol) was slowly added and the mixture was left under stirring at 0° C. for 1 hour then at room temperature overnight. Next morning HPLC showed no starting material remaining volatiles were removed under vacuum and resulting crude was dissolved in DCM washed several times with water. Organic layers were dried over Na2SO4 and volatiles removed to afford 453 mg of the final compound as a brown oil. at 0° C the mixture was left at room temperature overnight were removed under vacuum resulting crude Organic layers were dried over Na2SO4 and volatiles removed

実験手順: Methyl 2-chloro-4-methylbenzoate (520 mg, 2.82 mmol) was dissolved in Dichloromethane (DCM) (15 mL) and at 0° C. Dibal-H (4.694 ml, 7.04 mmol) was slowly added. The mixture was left at 0° C. for 2H and then at room temperature overnight. Next morning HPLC showed no starting material remaining, reaction was quenched with Rochelle salt, and leaving under stirring for 1 hour and then it was extracted with DCM, dried and concentrated to afford 365 mg of the final compound, pure enough to be used in the next step. The mixture was left at 0° C. for 2H at room temperature overnight reaction was quenched with Rochelle salt leaving it was extracted with DCM dried concentrated

実験手順: as follows: To a solution of 2-chloro-4-methylbenzoic acid (2.18 g; 12.8 mmol) in THF (22 mL) was added dropwise a solution of BH3.THF in THF (25.6 ml; 1.00 mol/l; 25.6 mmol), at 0° C. Upon complete addition the resulting mixture was heated under reflux, for 3 hours. Subsequently, the mixture was cooled to 0° C., 1M aqueous HCl (30 mL) was added dropwise, and the mixture was stirred for 10 min. Et2O (100 mL) was added and the layers were separated. The organic layer was washed with 1M aqueous HCl (2×), 5% aqueous NaHCO3 (2×), and brine, dried (Na2SO4), filtered and concentrated in vacuo to afford (2-chloro-4-methyl-phenyl)-methanol (1.80 g), which was used as such. at 0° C Upon complete addition the resulting mixture was heated under reflux, for 3 hours the layers were separated The organic layer was washed with 1M aqueous HCl (2×), 5% aqueous NaHCO3 (2×), and brine dried (Na2SO4) filtered concentrated in vacuo
