Synthesis

Synthesis of bicyclo[4.2.0]octane-1,3,5-triene-7-ol: A solution of 1-acetoxybenzocyclobutene (33.9 g, 0.21 mol) and p-toluenesulfonic acid monohydrate (1.9 g, 0.01 mol) in methanol (100 mL) was stirred at room temperature for 24 h. Evaporate the solvent, add 50 mL of water, and extract three times with diethyl ether (150 mL). The ether solution was dried over magnesium sulphate, the solvent was evaporated, and recrystallisation yielded 21.4 g (85%) of bicyclo[4.2.0]octane-1,3,5-triene-7-ol (i.e. 1-hydroxybenzocyclobutene), a white powder^[1].
