Methyl Thio Acetaldoxime production method

First preparing ester:

${\text{H}}_{\text{3}}\text{C-}\underset{\underset{\text{O}}{\left|\right|}}{\text{C}}\text{-OH+HS-C}{\text{H}}_{\text{3}}\stackrel{\text{30--50 }{}^{\circ }\text{ C}\text{,-}{\text{H}}_{2}O}{\to }{\text{H}}_{\text{3}}\text{C-}\underset{\underset{\text{O}}{\left|\right|}}{\text{C}}\text{-S-C}{\text{H}}_{\text{3}}$

Second preparing oxim from ester:

${\text{H}}_{\text{3}}\text{C-}\underset{\underset{\text{O}}{\left|\right|}}{\text{C}}\text{-S-C}{\text{H}}_{\text{3}}\text{+}{\text{H}}_{\text{2}}\text{NOH}\stackrel{-H_{2}O}{\to }\text{HO-N=}\underset{\text{C}{\text{H}}_{\text{3}}}{\underset{|}{\text{C}}}\text{-S-C}{\text{H}}_{\text{3}}$
