RESUMEN
A regioselective oxidation of N-indan-4-yl-acetamide or N-(5,6,7,8-tetrahydronaphthalen-1-yl)acetamide with potassium permanganate followed by acidic hydrolysis gave 7-aminoindan-1-one or 8-aminotetral-1-one in good yield. The amino ketones were converted to the corresponding 7-haloindanone or the 8-halotetralone. Another method to prepare 7-haloindan-1-ones was completed by a cyclization of 3-chloro-1-(2-halophenyl)propan-1-one under Friedel-Crafts conditions to produce the product in gram quantity.

The design of bone-targeted pyrido[2,3-d]pyrimidin-7-ones as Src tyrosine kinase inhibitors is described. Leveraging SAR from known compounds and using structure-based methods, we were able to rapidly incorporate bone binding components, which maintained, and even increased potency against the target enzyme. Compound 4 displayed a high affinity for hydroxyapatite, a major constituent of bone, and demonstrated antiresoprtive activity in our cell-based assay.
