[0453] Heated 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carbaldehyde (CAS No. 958230-19-8) (from Adesis, Cat. No. 4-263; Synnovator, Cat. No. PBN2011188: 2.71 g, 15 mmol ) and methylamine (33 wt.% in ethanol, 24 mL, 200 mmol) in 2-methoxyethanol (6 mL) to 110 °C and stirred overnight in a sealed pressure flask. The reaction mixture was then cooled to room temperature and concentrated. The residue was dissolved in HCl solution (1 N, 25 mL) and heated to 50 °C. After stirring for 2 hours, the reaction mixture was cooled to room temperature and washed with saturated NaHCO 3 Solution neutralization. The pale yellow precipitate was collected by filtration, washed with water and hexanes, then dried in vacuo to afford the desired product (2.54 g, 97%) as a pale yellow solid. C...

Description
field of invention [0001] The present invention relates to tricyclic compounds which are inhibitors of one or more FGFR enzymes and are useful in the treatment of FGFR-related diseases such as cancer and pharmaceutical compositions comprising said tricyclic compounds. Background of the invention [0002] Fibroblastgrowth factorreceptor (FGFR) is a receptortyrosinekinase that binds fibroblastgrowth factor (FGF) ligand. There are four FGFR proteins (FGFR1-4) that are capable of binding ligands and are involved in the regulation of many physiological processes including tissue development, angiogenesis, wound healing and metabolic regulation. Following ligand binding, receptors undergo dimerization and phosphorylation, resulting in the stimulation of proteinkinase activity and the recruitment of a number of intracellular docking proteins. These interactions contribute to the activation of a series of intracellular signaling pathways important for cell growth, proliferati...
