Versuchsvorschrift

A cooled (0° C.) mixture of (6-methoxynaphthalen-2-yl)methanol (90 mg; 0.48 mmol) in anh. DCM (2 ml) was treated dropwise with SOCl2 (89 mg; 0.75 mmol), and the resulting mixture was stirred at rt, under nitrogen, for 17 h. The volatiles were removed under reduced pressure, and the solid residue was triturated with Et2O. Filtration afforded 2-(chloromethyl)-6-methoxynaphthalene which was directly used for the next reaction. LC-MS (conditions E): tR=0.75 min.; no ionisation.
