Butacaine is a white crystalline ester used as a local anesthetic.[1] It was first marketed in 1920.[1]

Synthesis

The addition of metallic sodium is added to a mixture of allyl alcohol (1) and dibutylamine (2)[2] gives the conjugate addition product 3-dibutylamino-1-propanol (3). Esterification of this intermediate with para-nitrobenzoyl chloride (4) gives the ester 5. The reduction of the nitro group completes the synthesis of butacaine (6).[3][4][5][6][7][8]
