该中间体在本合成路线中的序号：(IV)The Grignard condensation of 4'-[2-(dimethylamino)ethoxy]-2-(4-isopropylphenyl)butyrophenone (I) with 4-(2-tetrahydropyranyloxy)phenylmagnesium bromide (II) in refluxing THF gives the triphenylbutanol derivative (III). The dehydration and deprotection of (III) by means of HCl in ethanol yields (E)-4-[1-[4-[2-(dimethylamino)ethoxy)phenyl]-2-(4-isopropylphenyl)-1-butenyl]phenol (IV), which is finally esterified with POCl3 in pyridine and hydrolyzed with NaHCO3 in ice water followed by acidification with concentrated HCl.
