Usage

Description

Cetilistat Intermediate is a chemical compound that serves as a key intermediate in the synthesis of the pharmaceutical drug cetilistat, a medication designed for weight loss. It is an essential component in the manufacturing process of cetilistat, contributing significantly to the drug's effectiveness as a weight management treatment.

Uses

Used in Pharmaceutical Industry:
Cetilistat Intermediate is used as a crucial component in the production of cetilistat, a weight loss medication. It plays a significant role in the development of this medication, ensuring its effectiveness in managing weight.
Cetilistat Intermediate is used as an intermediate in the synthesis of cetilistat for its weight loss properties, as it inhibits the enzyme lipase, which is responsible for breaking down dietary fat in the intestine. This inhibition prevents the absorption of fat, thereby aiding in weight reduction.

NOVEL PROCESSES FOR THE PREPARATION OF 2-OXY-BENZOXAZINONE DERIVATIVES

Provided herein are novel, commercially viable and industrially advantageous processes for the preparation of 2-hexadecyloxy-6-methyl-4H-3,1-benzoxazin-4-one, and its intermediates, in high yield and purity.

A he west for favorable department method of preparation

The invention discloses a method for preparing cetilistat, which belongs to the technical field of the medicine preparation method, and is used for solving the problems of high three wastes, low yield and high cost in the current preparation method. The method comprises the following steps: 1)esterifying a compound A(2-amino-5-methyl benzoic acid) or its salt; 2) acylating an esterification object in the step 1) and chloroformic acid n-cetanol ester; 3)removing ester group of the compound obtained in the step 2) to obtain 2-(cetane carbonyl oxygen)amino-5-methyl benzoic acid; and 4)cyclizing the compound in the step 3) to obtain the target products. By improving the production steps, the invention provides the synthetic method with simple operation, high efficiency, and convenient industrial production for the cetilistat product.

One-pot high-yielding preparation of cetilistat

The invention relates to a new process for one-pot preparation of cetilistat; the one-pot reaction is adopted, separation steps are sample, the product yield is high, the product quality is good, and the new process is especially suitable for industrialized production.
