Synthesis and local anesthetic properties of secondary alkoxyalkylaminoacylanilides.
Nineteen secondary alkoxyalkylaminoacylanilides were prepared. They were weaker bases and were more hydrophilic than the corresponding analogs lacking the ether function. In 2% solution, these compounds blocked the rat sciatic nerve in vivo after relatively short onset times with good frequency of anesthesia. The duration of block was 0.4--1.5 times that of lidocaine. Their systemic toxicity was low, and their irritation liability in most instances was acceptable.
