Versuchsvorschrift

4-Bromo-naphthalene-1-carbonyl chloride (13.8 g) was dissolved in dichloromethane (130 mL) and cooled to 0° C. TMS diazomethane solution (40 mL, 2 M in DCM) was added, and ice bath was removed. Reaction mixture was stirred for 18 hours and evaporated under vacuum, giving 1-(4-bromonaphthalen-1-yl)-2-diazoethanone (13.8 g, crude) as a brown oil.
