There is disclosed a compound of Formula (I):and any pharmaceutically acceptable salt or
zwitterion thereof; wherein: R is
hydrogen, methyl or ethyl; R1 is
hydrogen or C1-C2 alkoxy; R2 is methyl or a C2-C4 group which may be saturated or unsaturated, branched or linear; and R3, R4, R5 and R6 each are independently selected from
hydrogen, hydroxyl,
halogen, methyl optionally substituted with hydroxy, methoxy, ethoxy, and a saturated or unsaturated C2-C3 that may be optionally substituted with hydroxyl, with the provisos that: (i) at least two of R4, R5, R6 and R7 must be hydrogen, and (ii) R3, R4, R5 and R6 may be selected such that an adjacent pair thereof join to form a ring having at least 5 members. The compound of Formula (I) is believed useful in treating a
disease or disorder in a subject which may be alleviated by a 5HT2A
agonist (e.g., CNS disorders and one or more symptoms of any one of depression, alcoholism, tobacco
addiction, cocaine
