The present invention relates to Cyclic Phosphate Substituted Nucleoside Compounds of Formula (I), and pharmaceutically acceptable salts thereof, wherein A, B, R1, R2, R3, Q and V are as defined herein. The present invention also relates to compositions comprising a Cyclic Phosphate Substituted Nucleoside Compound, and methods of using the Cyclic Phosphate Substituted Nucleoside Compounds for treating or preventing HCV infection in a patient.
New water soluble benzimidazoles with a high degree of stability, which are substituted at the 1-position with carboxyalkoxycarbonyl substituents and at the 2-position with a 4-thiazolyl group are effective fungicides and anthelmintics. The compounds as well as processes for their preparation are described along with antifungal and anthelmintic compositions for their use. The 1-position substituent is a carboxyalkoxycarbonyl group of from 3 to 11 carbon atoms including certain salts and derivatives of the carboxy group. The compounds are generally prepared by contacting a 1-unsubstituted benzimidazole with a protected carboxyalkoxycarbonyl chloride.

The present invention relates to a process for preparing the hexanoic acid, 6-(nitrooxy)-, (1S,2E)-3-[(1R,2R,3S,5R)-2-[(2Z)-7-(ethylamino)-7-oxo-2-hepten-1-yl]- 3,5-dihydroxycyclopentyl]-1-(2-phenylethyl)-2-propen-1-yl ester of formula (I). In accordance with the present invention, the compound (I) can be efficiently prepared with high purity by coupling bimatoprost in a boronate protected form with 6-(nitrooxy)hexanoyl chloride and removing the boronate protecting group. The 6-(nitrooxy)hexanoyl chloride intermediate is prepared by ring-opening reaction of 2-caprolactone and subsequent nitration of the 6-hydroxyhexanoic acid potassium salt with a mixture of HNO3 and H2SO4 in dichloromethane.
