Novel crystalline forms of two indole compounds connected to phenoxyalkylcarboxylic acid groups are selective PPAR gamma partial agonists that are useful in the treatment of type 2 diabetes, hyperglycemia, obesity, dyslipidemia, and the metabolic syndrome. The novel crystal forms include a crystalline free acid dihydrate and crystalline free acid anhydrate of one compound and several crystalline forms of the free acid and the sodium salt of the second compound. The invention also relates to pharmaceutical compositions comprising these novel crystal forms, processes to prepare the crystal forms and their pharmaceutical compositions, and uses of the crystal forms in the treatment of type 2 diabetes and other PPAR gamma modulated diseases.

arylation reaction between 2-nitro-4-trifluoromethoxyaniline and isopropenyl acetate and subsequent reductive cyclization. The α-aryloxybutanoic acid was prepared via an asymmetric hydrogenation of the corresponding α-aryloxy-α,β-unsaturated acid. Tetrabutylammonium iodide-catalyzed coupling of the two fragments and ester hydrolysis completed the convergent synthesis. The described convergent synthesis was
