Teniloxazine
Chemical compound
From Wikipedia, the free encyclopedia
Teniloxazine (Lucelan, Metatone), also known as sufoxazine and sulfoxazine, is a drug which is marketed in Japan.[1] Though initially investigated as a neuroprotective and nootropic agent for the treatment of cerebrovascular insufficiency in the 1980s,[2][3][4][5][6][7][8][9] it was ultimately developed and approved as an antidepressant instead.[10] It acts as a potent norepinephrine reuptake inhibitor, with fair selectivity over the serotonin and dopamine transporters, and also behaves as an antagonist of the 5-HT2A receptor.[7][10][11]

Synthesis
Amide formation between 1-(Benzylamino)-3-{2-[(thiophen-2-yl)methyl]phenoxy}propan-2-ol [62473-86-3] (1) and Chloroacetylchloride [79-04-9] (2) gives PC13682456 (3). In the presence of sodium metal closing of the ring morpholine occurs to give PC13682470 (4). Lactam reduction with lithium aluminium hydride affords 4-Benzyl-2-({2-[(thiophen-2-yl)methyl]phenoxy}methyl)morpholine [62473-77-2] (5). Treatment with Ethyl chloroformate [541-41-3] (6) gives the urethane and hence 4-Ethoxycarbonyl-2-[2-(2-thenyl)-phenoxymethyl]morpholine, PC21482171 (7). Hydrolysis of the carbamate in the presence of barium hydroxide completes the synthesis of Teniloxazine (8).
Alternately, base reaction between 1-[2-(2-thenyl)phenoxy]-2,3-epoxypropane [55506-46-2] (9) and 2-Aminoethyl hydrogen sulfate [926-39-6] (10) is another way to perform the synthesis.
