反応手順

The resulting nitrohexanol acetate of formula 9 is then reduced using a boron-based reducing agent, e.g., sodium borohydride, in a 2° or 3° alkanol at 25°-80° C. for 3-15 hours to produce a nitrohexane derivative of formula 10 (step 8). For example, O-acetyl-1-(3,4-dimethoxyphenyl)-2-nitro-6-cyano-6-(i-propyl)-6-(3,4-dimethoxyphenyl)hexan-3-ol (9) is heated with NaBH4 in 2-propanol at reflux for 3-15 hours to yield 1-(3,4-dimethoxyphenyl)-2-nitro-6-cyano-6-(prop-2-yl)-6-(3,4-dimethoxyphenyl)hexane (10).
