実験手順

Alternatively, one may prepare compounds of the invention via the procedures of Scheme III. In the first step, a derivative of formula 6a (see Scheme II) is alkylated with a 1,3-dihalopropane using a strong base in a suitable aprotic solvent to produce a derivative of formula 21 (step 1). For example, 2-(3,4-dimethoxyphenyl)-2-isopropylacetonitrile is treated with sodium amide in toluene and 1-bromo-3-chloropropane to produce 2-(3,4-dimethoxyphenyl)-2-isopropyl-2-(3-chloropropyl)-acetonitrile (21).
