Synthesis

File:Phenaglycodol synthesis.svg
Jack Mills "2-chlorophenyl-3-methyl-2, 3-butanediols" U.S. Patent 2,812,363 (1957 to Eli Lilly Co.).

p-Chloroacetophenone and NaCN are reacted together to give the corresponding cyanohydrin (cf Strecker synthesis). The cyano group is then partially hydrolyzed in acid to the corresponding amide, thus p-chloroatrolactamide (4) is formed. The amide group is then further hydrolyzed with a 2nd equivalent of water in concentrated lye to p-chloroatrolactic acid (5); this is then esterified to Ethyl p-chloroatrolactate (6). Finally, nucleophilic addition a couple of equivalents of MeMgI are added to the ester give Phenaglycodol (7) crystals.
