Disclosed are chemical entities which are compounds of Formula (I) and pharmaceutically acceptable salts thereof, wherein Formula (I) has the structure: R1a, R1b, R2, R3, R4a, R4b and Y are as defined herein. These chemical entities are useful for reduction of very long chain fatty acid levels. These chemical entities and pharmaceutically acceptable compositions comprising such chemical entities can be useful for treating various diseases, disorders and conditions, such as adrenoleukodystrophy (ALD).
Abstract A key intermediate was obtained as solid through filtration of the reaction mixture of saccharin, chloro(triphenyl)phosphonium chloride, and N,N-diisopropylethylamine (DIPEA) in chloroform. The soluble triphenylphosphine oxide went to filtrate as waste, while the solid was reacted with amines to afford N-sulfonylamidines. In total, 26 N-sulfonylamidine products were obtained in moderate to
