実験手順

To a 100 ml round-bottom flask containing (6aR,9R)-7-phenylcarbamoyl-4,6,6a,7,8,9-hexahydro-indolo[4,3-fg]quinoline-9-carboxylic acid methyl ester (0.8 g, 2.06 mmol) is added methanol (12 ml), THF (24 ml) and a solution of lithium hydroxide (247 mg) in water (12 ml). The reaction mixture is stirred at room temperature for 20 minutes by which time TLC in 20% methanol/dichloromethane showed complete conversion of starting material. The colour of the crude reaction mixture has changed from light yellow to a violet red. The volatiles are removed in vacuo (leaving only water) and the aqueous solution made acidic with the addition of 1 M HCl. The resulting beige precipitate is filtered at the pump and the filter cake washed with distilled water (50 ml). The filter cake is then dried in a high vacuum oven at 50° C. for 16 hours providing product.
