Methyl 4-(Butyrylamino)-3-Methyl-5-Nitrobenzoate (CAS: 152628-01-8) is a useful synthetic intermediate in the production of Telmisartan (CAS: 144701-48-4), an antihypertensive drug. Methyl 4-(Butyrylamino)-3-Methyl-5-Nitrobenzoate is part of a more efficient process of synthesizing Telmisartan in terms of impurity, yield, cost, and large-scale production. Telmisartan is an angiotensin II receptor blocker (ARB) indicated for: Treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. Cardiovascular (CV) risk reduction in patients unable to take ACE inhibitors.
