Shulgin's TiHKAL synthesis #2 DBT.
TRYPTAMINE, N,N-DIBUTYL. EXTENSIONS AND COMMENTARY : The earliest reports that mention any human responses to DBT suggested that with an i.m. injection of 1 mg/Kg there was less effect than with DMT or DET. This&report was discussed in the commentary on DMT and it was stated that the dihexyl- homologue (DHT) was without any activity at all. The monohexyl homologue has been described as being, "inactive in a few patients," but has not been systematically studied.
