$\text{CH}_3\text{OH} + \text{PCl}_5 \longrightarrow \text{CH}_3\text{Cl} + \text{POCl}_3 + \text{HCl}$
$\text{CH}_3\text{Cl} + \text{KCN (alc.)} \longrightarrow \text{CH}_3\text{CN} + \text{KCl}$
$\text{CH}_3\text{CN} + 2\text{H}_2\text{O} + \text{H}^+ \longrightarrow \text{CH}_3\text{COOH} + \text{NH}_4^+$
$\text{CH}_3\text{COOH} \xrightarrow{(1) \text{LiAlH}_4, \text{ ether} / (2) \text{H}_3\text{O}^+} \text{CH}_3\text{CH}_2\text{OH}$

$\text{C}_2\text{H}_5\text{ONa} + \text{C}_2\text{H}_5\text{Br} \xrightarrow{\Delta} \text{C}_2\text{H}_5-\text{O}-\text{C}_2\text{H}_5 + \text{NaBr}$
