Abstract: The present application relates to a novel and efficient process with high yield for preparing methyl {4,6-diamino-2-[5-fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]pyrimidin-5-yl}carbamate of the formula (I) in the crystalline form of modification I, wherein the x-ray diffractogram of the compound of the formula (I) in modification exhibits peak maxima of the 2 theta angle at 5.9, 6.9, 22.7, in very high purity which is significantly more cost-effective than the process known from the art and can be performed in customary pilot- and production plant-equipment (stirred tank/devices for isolation).

Abstract: The present invention relates to a novel and improved process for preparing butyl (5S)-5-({2-[4-(butoxycarbonyl)phenyl]ethyl}[2-(2-{[3-chloro-4?-(trifluoromethyl)[biphenyl]-4-yl]methoxy}phenyl)ethyl]amino)-5,6,7,8-tetrahydroquinoline-2-carboxylate of the formula (XII) to novel precursors for preparation thereof, and to use for preparation of (5S)-5-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)[biphenyl]-4-yl]methoxy}phenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid.

Abstract: A process for the preparation of pyrazolopyrolidines of structural formula I: and W is or P, wherein in P is an amine protecting group. These compounds are useful in the synthesis of dipeptidyl peptidase-IV inhibitors for the treatment of Type 2 diabetes. Also provided are useful intermediates obtained from the process.
