Abstract

2,2-Dimethyl 5- (2,5-dimethyl phenoxy) valeric acid is made by (a) reacting 1-bromo 3-(2,5-dimethyl phenoxy)propane with an alkyl methyl malonate CH3CH(COOR)2, in which R is methyl or ethyl in presence of sodium alkoxide and the corresp. alcohol; (b) hydrolysing with aq. alkali metal hydroxide at b.pt. and acidifying; (c) treating with lithium diisopropylamide in molar ratio 1:2 in THF soln; (d) methylating the Li salt obtd in alpha-posn. to the COOH gp by treatment with methyl chloride, bromide or iodide; and (e) acid hydrolysis of the prod.
