Methyl 4-cyclopentyl-3-(trifluoromethyl)benzoate

It serves as a structural precursor to the aromatic portion of the Etrasimod molecule, specifically forming the 4-cyclopentyl-3-(trifluoromethyl)benzyl ether part that is attached to the tetrahydrocyclopenta[b]indole core. Methyl 4-cyclopentyl-3-(trifluoromethyl)benzoate is a key intermediate in the synthesis of Etrasimod, an S1P1 receptor modulator used for treating ulcerative colitis and other autoimmune disorders.
