Yield: 100%

Reaction Conditions:

with sodium tetrahydroborate in ethanol at 10 - 20; for 3 h;

Steps:

4 liquid crystal compound 3RIGUQUF
168.8g compd. 6 and 650 ml of ethanol is added during the reaction of the bottle. Next, the water temperature is lower than 10 °C, NaBH445g of small amounts of added. Next, raised in temperature to room temperature, the reaction solution is a 3-hour continuous agitation. After the reaction is completed, ethanol is removed, then the hydrolysis of 10% HCl 450 ml is added is in order. The mixture is extracted by dichlomethane, thereafter is washed with water, dried and then, the solvent is removed, 170g compd. 7 in which yield 100% (corallite solid). The reaction of the pathway of the following relationships.
