Methanol → HCID 20515678, compound

Participants

Reaction Steps

A mixture of 1-(2-carbomethoxyethyl)-2-cyclopropyl-3-(3-pyridylmethyl)indole (1.0 g), sodium hydroxide (0.18 g), methanol (1 ml) and water (10 ml) was heated under reflux for six hours. The resulting solution was evaporated to dryness and the residue was dissolved in a small volume of water. Acidification with acetic acid gave a solid which was filtered off, washed with water, dried and crystallised from isopropanol/petrol (b.p. 60°-80°) to give 1-(2-carboxyethyl)-2-cyclopropyl-3-(3-pyridylmethyl)indole (0.55 g), m.p. 159°-160°.
