Thiophene derivatives of formula (I) and a pharmaceutically acceptable salt thereof are provided. These compounds have utility for the treatment or prevention of disorders caused by IgE, such as allergy, type 1 hypersensitivity or familiar sinus inflammation.
therapeutics and to reduce the time-to-market time-span. Following this concept a small library of compounds was screened for their ability to act as inhibitors of acetyl- and butyrylcholinesterase. Picloxydine, an established antiseptic, was shown to be an inhibitor for both enzymes. Systematic variation of the aryl substituents led to analogs possessing almost the same good properties as gold standard galantamine
A novel process for the preparation of Etravirine comprises the condensing of ethyl cyanoacetate with N-cyanophenylguanidine to obtain an —OH compound of formula (II), which is further converted to a leaving group of formula (III). The compound of formula (III) is optionally protected and brominated to yield compound of formula (IV). The condensation of formula (IV) with 3,5-dimethyl-4-hydroxybenzonitrile yields a compound of formula (VI), and an optional deprotection of the compound of formula (VI) results in Etravirine.

The present invention relates to a novel process for the preparation of Etravirine, comprises; condensing ethyl cyanoacetate with N-cyanophenylguanidine to obtain -OH compound of formula (II), which is further converted to a leaving group of formula (III). Compound of formula (III) is optionally protected and brominated to yield compound of formula (IV). Condensation of formula (IV) with 3,5-dimethyl-4-hydroxybenzonitrile gives formula (VI), and an optional deprotection of formula (VI) results into Etravirine. The present invention further relates to process for purifying Etravirine. The present invention also provides novel intermediates of Etravirine.
