Versuchsvorschrift

The reaction mixture containing 1-(3,4-dimethoxyphenyl)-2-nitro-3-acetoxy-6-cyano-6-(i-propyl)-6-(3,4-dimethoxyphenyl)hexane (9) prepared in Preparation 7(A) was cooled to room temperature and diluted with isopropanol (350 mL). Solid NaBH4 (15 g, 0.4 mol) was added over 15 minutes at 25° C. The mixture was then heated to reflux (about 40° C.) for 15 hours, then cooled to 5° C. A solution of 10% HCl (30 mL) was slowly added, followed by water (100 mL). The organic layer was extracted, washed with saturated aqueous NH4Cl (200 mL), and saturated aqueous NaHCO3 (200 mL). The organic layer was evaporated to yield 1-(3,4-dimethoxyphenyl)-2-nitro-6-cyano-6-(i-propyl)-6-(3,4-dimethoxyphenyl)hexane (10, 58.7 g, m.p. 107°-110° C., MS m/e 470(M+)) as a pale yellow solid.
