Reaction Steps
86.25 g Of small pieces of sodium are added to 60 g of 2-carbethoxy-methyl-2-hydroxy-decalin and 900 ml of anhydrous ethyl alcohol. A vigorous reaction sets in which causes the reaction medium to reflux. Reflux is maintained for 1 hour. The mass is cooled, 1000 ml of water added, the alcohol distilled off and the residue is taken up in a little warm water. After cooling the mass is extracted three times with 250 ml of diethyl ether. The ethereal solutions are washed to neutrality and distilled; there are thus obtained 40 g of crude product which are rectified under 0.5 mm. This rectification gives 22 g of 2-hydroxyethyl-2-hydroxy-decalin (b.p.0.5 = 138°-140°C), which represents a conversion of about 42%.
