The resulting imine of formula 24 is then deprotonated using a suitable strong base, and allowed to react with a compound of formula 22 to produce a compound of formula 25 (step 2). For example, 1-(carboethoxy)methyliminomethyl-3,4-dimethoxybenzene (24) is suspended in a solution of LiNiPr2 in THF/HMPA at -78° C., then reacted with 2-(3,4-dimethoxyphenyl)-2-isopropyl-2-(3-iodopropyl)acetonitrile (22) to produce N-[1-carboethoxy-5-(3,4-dimethoxyphenyl)-5-cyano-5-(isopropyl)pentyl]iminomethyl-3,4-dimethoxybenzene (25).
