CRYSTALLINE FOSAMPRENAVIR CALCIUM AND PROCESS FOR THE PREPARATION THEREOF

摘要

The main object of the present invention relates to novel crystalline form of Fosamprenavir Calcium designated as Form A. Another object of the present invention relates to a process for the preparation of Crystalline Form A of Fosamprenavir Calcium. Yet another object of the present invention relates to crystalline Form A of Fosamprenavir Calcium characterized by an PXRD diffraction having reflections at about 3.1 ± 0.2, 4.4 ± 0.2, 5.0 ± 0.2, 6.3 ± 0.2, 7.4 ± 0.2, 8.0 ± 0.2, 28.
