This paper describes a practical approach to the preparation of 4-(2-hydroxyethyl)indolin-2-one, a key intermediate in the synthesis of dopaminergic agonists such as ropinirole - a drug used in the treatment of Parkinson's disease and restless legs syndrome - and of two sets of protein kinase inhibitors. The sequence starts from commercially available 2-(2-methyl-3-nitrophenyl)acetic acid, which is converted in five steps into the desired target compound. This procedure offers a convenient alternative route to existing methodologies, given its milder reaction conditions, ease of implementation, and its overall yield (59 %).
