A simple and efficient synthesis of novel 6-aminomethyl-tetrahydroindol-4-ones, which are butyrophenone analogues of molindone, is described. These compounds exhibit potent affinities for D-2 and 5-HT2A receptors in vitro. The most active compounds, 6d (QF 0408B) and 6e (QF 0409B), with pK(i) (5-HT2A/D-2) ratios of 1.32 and 1.17 respectively, show an antipsychotic profile according to Meltzer's classification.

We describe the synthesis of 5-aminoethyl- and 6-aminomethyl-4-oxotetrahydroindoles as butyrophenone derivatives in the indole series, as potential atypical antipsychotics. The affinities of these compounds for serotonin (5-HT2A) and dopamine (D2) receptors were evaluated in vitro. The ratios of pKi's for 5-HT2A/D2 receptors may be useful for rapid screening of new compounds and assessing potential induction of extrapyramidal symptoms; ratio values ≥1.12 (Meltzer's ratio) are predictive of an atypical antipsychotic profile. Compounds 26e (QF 0408B) and 26f (QF 0409B) showed high affinity for both D2 and 5-HT2A receptors, and their MEltzer's ratios were 1.32 and 1.17 respectively, while haloperidol showed a ratio of 0.93.
