Mepindolol (Betagon) is a non-selective beta blocker. It is used to treat glaucoma.^[1]

Synthesis

The first reported synthesis of mepindolol in 1971 used 4-hydroxy-2-methylindole {9) with epichlorohydrin and then isopropylamine to add the sidechain which was known to produce beta blockers, by analogy with drugs discovered by Imperial Chemical Industries, such as propanolol.^[2] The requisite intermediate was synthesized in a multi-step procedure from 4-benzyloxyindole-2-carboxylic acid (1) which was converted into (9) by conventional chemistry.^[3]^[4]
