Butacaine is a white crystalline ester used as a local anesthetic.

Synthesis[edit]

The addition of metallic sodium is added to a mixture of allyl alcohol (1) and dibutylamine (2)^[1] 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).^[2]^[3]^[4]^[5]^[6]^[7]
