Chapter 19, Problem 19.20P

Interpretation Introduction

Interpretation:

It is to be shown how to carry out the given synthesis.

Concept introduction:

A Williamson ether synthesis is the method of ether synthesis in which the alkyl halide is treated with an alkoxide ion. Sodium borohydride (${\text{NaBH}}_{\text{4}}$) is the reducing agent and selectively used to reduce aldehyde and ketone group to corresponding alcohols. To protect an alcoholic group, it is converted to its silyl ether derivatives like OTBDMS, which is stable under the basic condition or through other protecting groups.
