This application claims priority to United States Provisional Patent ation serial number 62/434,839 filed on er 15, 2016, the entirety of which is hereby incorporated by reference.

Field of Invention The present invention is directed to inhibitors of tyrosine-protein kinase Kit (c-Kit) useful in the treatment of diseases or disorders associated with c-Kit. Specifically, the invention is concerned with compounds and compositions inhibiting c-Kit, methods of treating diseases or disorders associated with c-Kit, and methods of synthesis of these compounds.

Background of the Invention The discovery that the tyrosine kinase inhibitor (TKI) imatinib inhibits Kit, and its introduction as a treatment, transformed the clinical management of gastrointestinal stromal tumors (GIST) (Corless, C.L. et al., Nat. Rev. Cancer. 2011; 11: 865-78). Nonetheless, most imatinib-treated patients ultimately relapse due to outgrowth of clones with secondary, drugresistant KIT ons (Heinrich, M.C., et al., J. Clin. Oncol. 2006; 24: 4764-74). Secondary mutations typically occur in the ATP binding pocket encoded by exons 13 and 14, and the activation loop (A-loop) encoded by exons 17 and 18. The challenge of treating imatinib ant GISTs is compounded by mutational heterogeneity, as patients can harbor multiple different ary mutations in distinct tumor lesions, or even within different regions of the same lesion (Wardelmann E., et al., Clin. Cancer Res. 2006; 12: 1743-9).

GIST ts with imatinib-resistant tumors are treated with sunitinib, which potently inhibits KIT ATP-pocket mutants (Heinrich, M.C., et al., J Clin Oncol 2008; 26: 5352- 9). However, nib is ineffective against A-loop mutants, which account for 50% of imatinib-resistance mutations. This may explain why overall response rates (ORR) are low (7%) and median progression-free survival (PFS) is short (6.2 months) (Demetri, G.D., et al., Lancet 2006; 368: 1329-38). fenib was recently approved as third line therapy, but also shows only te activity, with ORR of 4.5% and median PFS of 4.8 months (Demetri, G.D., et al., Lancet 2013; 381: 295-302). The Kit inhibitory ties of regorafenib have not yet been analyzed extensively, but both clinical and initial preclinical data suggest a limited spectrum of sensitive KIT mutants (George, S., et al., J. Clin. Oncol. 2012; 30: 2401-7; 1004458711 Serrano-Garcia, C., et al., ASCO Meeting Abstracts 2013; 31(15_suppl): 10510). Thus, additional agents are needed to overcome resistance mutations in KIT, in particular those in the The Kit inhibitors imatinib, sunitinib and regorafenib are effective GIST therapies, though most patients develop resistance to these drugs due to somatic acquisition of polyclonal secondary Kit mutants. The lack of efficacy of any single agent against the te set of ial ATP-binding pocket and A-loop secondary mutants makes achievement of prolonged complete disease control in late stage patients challenging. To address this unmet medical need, presented herein, are compounds that target a broad range of primary and secondary Kit mutants, including those within the A-loop.

Viral particles were produced by transfecting pLVX-IRES-puro vectors containing KIT mutant genes into HEK293 cells (Invitrogen) using the Trans-Lentiviral ORF Packaging Kit (Thermo Scientific). 48 hours post-transfection, virus-containing supernatants were harvested and incubated for another 48-72 hours with parental Ba/F3 cells (DSMZ) in the presence of 10 ng/mL IL-3 (R&D Systems). Transduced Ba/F3 cells were then selected by IL- 3 withdrawal and puromycin (0.5-1 µg/mL, Invitrogen).

Viability assays ] Cell lines (i.e., EX11DEL, EX11DEL/D816H, EX11DEL/T670I, and EX11DEL/V654A) were plated into 384 well plates using RPMI 1640 mented with 10% FBS at densities that produced linear growth and incubated at 37 °C in 5% (v/v) CO2. Cells were treated with eight trations of compound over a 4-fold dilution (10 µM to 0.61 nM) and viability was assessed using Cell Titer-Glo assay (Promega) after 72 hours. Data were plotted as percent viability relative to vehicle-treated cells. Dose-responses curves were generated and used to ate IC50 values.
