Short Description


A process for continuous flow synthesis of >99.98% pure ß- amino crotonates which are intermediates to Calcium Channel Blocker (anti-hypertensive drugs)

Abstract


BACKGROUND

ß-amino crotonates are generally produced by a batch synthesis procedure resulting in longer reaction times.


TECHNOLOGY DESCRIPTION

A novel production process for ß-amino crotonate using a continuous mode reactor, with reduced reaction time, yet resulting in higher yield (>93%) and high-purity end-product (>99.98%). The process can be catalytic or catalysis- free : used to produce ß-amino crotonate and its analogues.


MARKET POTENTIAL
• In Asia, an estimated 200 million people suffer from hypertension*
• Calcium channel blockers help to decrease the heart rate, which can further lower the blood pressure, relieve the chest pain and control an irregular beat**- hence their use a hypertensive drugs
• The world market for anti-hypertensive drugs is targeted to exceed $66.2 billion by the year 2015^

VALUE/ADVANTAGES
• Catalytic as well as a catalyst, free continuous process
• ß amino crotonate yielded is of high purity- process provides a better control on product profile
• Reduced reaction time
• Can be prepared from a variety of amines and beta keto esters


APPLICATIONS
• An intermediate in the synthesis of Ca channel blockers such as amlodipine, nisoladipine, benidipine, nicardipine, etc
• Ca channel blockers are used as intermediates in preparation of anti-hypertensive drugs


TECHNOLOGY STATUS
• Demonstrated at the lab scale
• On the lookout for potential partners for spin-off and licensing
• Patent application filed: Indian- 1025/DEL/2011
