They car- rier' out the reduction the addition of sodium in large nieces to the e^ter dissolved in absolute thanol. This method, which uses a large excess of sodium and alcohol, has uroved very conveni- ent in synthetic organic research and is still a recommended croce- dure (?). However, this method has several disadvantages as a commercial oreparatlon of alcohols. A considerable amount of solium is V.

Chromium reduction is achieved the addition of chemicals such as ferrous sulfate, sodium dioxide, or sodium bisulfate/metabisulfate into a tank where pH is controlled to low levels (usually pH 23).

Hydride addition the use of complex metal hydrides (LiAlH4) results in the reduction of carbonyl compounds to alcohols (see Synthesis of alcohols, p. 44). The H anion is an extremely strong base, that is, a poor leaving group; consequently, this reaction is not reversible. Iii. Addition of nitrogen nucleophiles.

The term "readily cleavable alcohol protecting group" includes those alcohol protecting groups which can be cleaved off under conditions which do not affect an alkoxy group.

It is prepared condensation of ethylcyanoacetate with 2-chloro-3-pentyne in presence of sodium ethylate yields ethyl-1-methyl-2-pentnyl cyanoacetate which on further condensation with allylbromide yields ethyl(1-methyl-2-pentynyl)allylcyanoacetate. Reaction with N-methyl urea yields the iminobarbituric acid which on acid catalyzed hydrolysis forms methohexital. Prepare some sodium ethylate dissolving a piece of sodium the size of a pea in i cc. Of absolute alcohol in a tCbt-ttibe. If the alcohol is absolute and the solution sufficiently concentrated, will solidify on cooling. Notice also that such a solution darkens rapidly on exposure to the air while a solution of sodium hydroxide in pure alcohol An example of this will be found in * Tables I. And II., where the recorded osmotic pressures are identical, 2.56 atmospheres, as are also the gas pressures, 2.43 atmospheres; and yet the ratio of osmotic to gas pressure in one case is 1.055, -nd in the other 1.051.

Pyrido[1,2-a]pyrimidines represent a simple bicyclic ring system that contains a nitrogen-bridgehead condensed pyrimidine moiety. Synthetic methods for these compounds can often be applied to the preparation of similar bi- and polycyclic ring systems.
