In order to find non-narcotic analgesics, 54 compounds of amino-tert-alcohol, in which a variety of substituent groups were involved at the carbon atom in 1-position and at the amino group, were synthesized by reacting various α-and β-amino acid esters with Grignard reagents. These amino acid esters were readily reacted with alkyl Grignard reagents to give the expected compounds. However, when bulky aromatic Grignard reagents were submitted to react, the reactions were found to stop at the stage of intermediate formation of the corresponding ketones.
