合成路线1
该中间体在本合成路线中的序号:(VIII)3,5-Diisopropyl-4-hydroxybenzaldehyde (VI) is esterified with acetyl chloride, producing acetate (VII). Subsequent Wittig condensation of aldehyde (VII) with carboethoxymethylene triphenylphosphorane leads to the cinnamyl derivative (VIII), which is further hydrogenated to the arylpropionic ester (IX). After saponification of ester (IX) with LiOH, the resultant carboxylic acid (X) is coupled to amine (V), producing amide (XI). Finally, amide reduction with borane in THF gives rise to the target amine.
