Versuchsvorschrift
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.
