- Efficient synthesis of (S)-2-(cyclopentyloxycarbonyl)-amino-8-nonenoic acid: Key building block for BILN 2061, an HCV NS3 protease inhibitor
-
A new procedure for the practical synthesis of (S)-2-(cyclopen- tyloxycarbonyl)amino-8-nonenoic acid, a key building block for BILN 2061, an HCV NS3 protease inhibitor, has been developed. The key step features a kinetic resolution of racemic 2-acetylamino-8-nonenoic acid with acylase I. In addition, the undesired (R)-2-acetylamino-8-nonenoic acid was recycled after racemization. The procedure was implemented for the production of (S)-2-(cyclopentyloxycarbonyl)amino-8-nonenoic acid on pilot-plant scale.
