Reaction Steps

1-(4-tert-Butylphenyl)-2-chloro-1H-indole-3-carboxaldehyde is reacted with 1-(2-aminoethyl)pyrrolidine as described in Step 2 of Example 29 to obtain oil. The oil is dissolved in small amount of methanol and treated with 1M ethereal hydrochloric acid. The solvents are removed and the residue is triturated with ether to yield 1-(4-tert-butylphenyl)-2-(2-pyrrolidin-1-yl-ethylamino)-1H-indole-3-carboxaldehyde hydrochloride (20% yield) as a light beige solid.
