Meprylcaine (also known as Epirocaine and Oracaine) is a local anesthetic with stimulant properties that is structurally related to dimethocaine.[1]

Meprylcaine has a relatively potent inhibitory action on the monoamine transporter and inhibits the reuptake of dopamine, norepinephrine and serotonin.[2][3]


Thieme Synthesis:[4] Patents:[5][6]

The 2-methyl-2-(propylamino)propan-1-ol [55968-10-0] (1) is treated with base and then with Benzoyl chloride (2), completing the synthesis of Meprycaine (3).
