Predict the product of hydrolysis of the above molecule.

Identify $X, Y$ and $Z$ respectively in the following reaction sequence:
$CH_3COOH$ $\xrightarrow[(ii) \Delta]{(i) NH_3} CH_3CONH_2$ $\xrightarrow[Pyridine / 343 \ K]{(iii) C_6H_5SO_2Cl} X + Y + Z$

$CH_3-C(=O)-O-CH_2-CH_3 + H-\bullet^- \to$ (where $\bullet = ^{18}O$) One of the products of the reaction is
