YieldReaction ConditionsOperation in experiment
76% at 160℃; for 0.666667h; A suspension of the corresponding methyl 2,3-dihydroxybenzoate (1 eq.) in dichlorodiphenylmethane (1.5 eq.) was stirred at 160 C. for 40 min. After cooling to 50 C., 30 mL MeOH was added to the viscous brown oil leading to the formation of a precipitate. The precipitate was filtered, washed with MeOH (3×20 mL) and dried under high vacuum to yield the desired compound as a colorless solid. ; <strong>[105603-49-4]Methyl 5-bromo-2,3-dihydroxybenzoate</strong> (3 g, 12.87 mmol, 1 eq.) was reacted with dichlorodiphenylmethane (3.7 mL, 4.58 g, 19.31 mmol, 1.5 eq.) according to GP2, Method A. Yield: 4 g (76%). Colorless powder. Mp.: 146-148 C.

YieldReaction ConditionsOperation in experiment
91% In toluene;Heating / reflux; <strong>[363-52-0]3-Fluorocatechol</strong> (12.81 g, 100 mmol) and dichlorodiphenylmethane (23.71 g, 100 mol) were dissolved in toluene (250 ml) and heated at reflux overnight. The solvent was evaporated and the residue was chromatographied on silica gel (200 g, [1/1] Dichloromethane/n-hexane eluant) to yield the ketal as a white crystalline solid (26.74 g, 91 percent). m. p.: [65-67°C.]
