実験手順

The product of stage (b) was suspended in 10 ml of boiling methanol and 0.55 g of potassium hydroxide in 5.5 ml of water was added dropwise over 15 mins. The mixture was refluxed until a dark red solution formed, (after ca. 6 hrs) when 2 ml of concentrated hydrochloric acid was cautiously added dropwise. The mixture was cooled and filtered, and the solid residue washed thoroughly with water. The water washings were re-acidified and filtered. The combined solid residues (500 mg) mp 200°-209°, were recrystallised from acetonitrile to give the title product as the trans-isomer (300 mg) m.p. 216°-219° C.
