Chemical Properties

White Solid


A long-acting β2 adrenoreceptor agonist and bronchodilator, for the treatment of asthma and chronic obstructive pulmonary disease.


ChEBI: A maleate salt obtained by reaction of indacaterol with one equivalent of maleic acid. Used for treatment of chronic obstructive pulmonary disease.

Clinical Use

Indacaterol is a b-adrenoceptor agonist currently approved in Europe as Onbrez, and is marketed by Novartis. It needs to be taken only once a day, unlike competitors formoterol and salmeterol. These drugs are used in the treatment of chronic obstructive pulmonary disease (COPD) and asthma. Onbrez is administered via an aerosol formulation through a dry powder inhaler. A Phase III trial published in July 2010 suggested that indacaterol is significantly more effective than twice-daily formoterol in improving FEV1 and reduces the need for rescue medication.

Chemical Synthesis

The synthesis of indacaterol relies on the union of the dihydroindeneamine region and the quinolinol region of the molecule. Preparation of the dihydroindene unit of indacaterol was reported by researchers at Novartis in 2006 and is summarized in the scheme. 2,3-Dihydro-1H-inden-2-amine (59) was protected as its trifluoroacetamide 61 and was followed by Friedel–Crafts alkylation with acetylchloride to give 62. Hydrogenative carbonyl reduction of this unsymmetrical dihydroindene provided amide 63. An iterative Friedel–Crafts acylation/hydrogenation sequence was used to install the second ethyl group, giving rise to trifluoroacetamide 64. Basic hydrolysis to remove the trifluoroacetamide functionality, followed by salt formation by means of gaseous HCl furnished the dihydroindene amine 65. The synthesis of the remaining portion of the molecule starts from 8-hydroxyquinoline (66). Friedel–Crafts alkylation with acetylchloride and trichloroaluminum installed the acetophenone functionality at the 5-position of the quinoline frame followed by benzyl protection of the hydroxyl group to give ether 67. Oxidation of quinoline 67 with mCPBA and acylation of the resulting N-oxide with acetic anhydride and thermal rearrangement produced quinolone 68. Bromination of the methyl ketone and subsequent asymmetric reduction provided (R)-alcohol 69. Bromohydrin 69 was then converted to the epoxide using potassium carbonate prior to amination of the epoxide with dihydroindene intermediate 65 to furnish the indacaterol skeleton 70. Hydrogenolytic debenzylation and maleate salt formation provided indacaterol maleate (XI).
