There total 5 articles about 4-[2-(1-Oxo-2,2-dimethylpropoxy)butoxy]benzoic acid ethyl ester which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 92.0%

ethyl p-<(2RS)-2-hydroxybutoxy>benzoate (56220-20-3) + pivaloyl chloride (3282-30-2) → ethyl p-<(2RS)-2-(t-butylcarbonyloxy)butoxy>benzoate, (56219-74-0,69522-82-3)

Guidance literature:

With pyridine; In benzene; Ambient temperature;

Reference yield: 89.0%

→ ethyl p-<(2RS)-2-(t-butylcarbonyloxy)butoxy>benzoate, (56219-74-0,69522-82-3) + pyridine hydrochloride (628-13-7)

Guidance literature:

Reference yield:

Ethyl 4-hydroxybenzoate (120-47-8) → ethyl p-<(2RS)-2-(t-butylcarbonyloxy)butoxy>benzoate, (56219-74-0,69522-82-3)

Guidance literature:

Multi-step reaction with 3 steps

1: 35 percent / Ph₃P, diethyl azodicarboxylate / 24 h / Ambient temperature

2: 95 percent / HCl / ethanol / 0.17 h / Ambient temperature
