[0318]

[0319] (i) Preparation of 4,6-dichloro-[1,3,5]triazin-2-ylamine derivative (2)

[0320] To a cooled (-60°C) solution of cyanuric chloride (1) (3.00g, 16.26mmol) in ethylene glycol dimethyl ether (40ml) was added the appropriate amine (2.80ml, 32.5mmol) dissolved in water (1.4 ml) solution. The amine solution was added dropwise over 10 minutes. The mixture was removed from the cold water bath and water (25ml) was added to completely quench the reaction. The quench mixture was stirred for 5 minutes before any precipitate was filtered off. The filter cake was washed with water (250ml) and dried in a vacuum desiccator to give the desired 4,6-dichloro-[1,3,5]triazin-2-ylamine, which was then further purified by making Recrystallization from a minimal amount of hot EtOAc afforded the product.

[0349] To a cooled (-5 °C) solution of 2,4,6-trichloro-pyrimidine (8) (2.73 mmol) in ethanol (6 ml) was added the appropriate amine (2.73 mmol), followed by dropwise addition of Et 3 N (0.303ml, 2.18mmol). The cooling bath was removed and the reaction was allowed to warm to room temperature. Water was then added to the mixture, resulting in the formation of a precipitate. The solid was removed by suction filtration and washed with icy EtOH (6ml) to give the desired product which was then purified by flash chromatography (eluent typically 100% hexane to 4:1-hexane:EtOAc)

Description

[0001] The present invention relates to compounds useful as mTOR inhibitors, their use and their synthesis. Background technique [0002] Growth factor / mitogenic activation of the phosphatidylinositol 3-kinase (P13K) AKT signaling pathway culminates in the critical cell cycle and growth control regulator mTOR, the mammalian target of rapamycin (alternatively referred to as FRAP (FKBP 12 and rapamycin-associated protein), RAFT1 (target of rapamycin and FKBP12 1), RAPT1 (target of rapamycin 1)—all derived from the association with the FK-506-binding proteins FKBP12 and SEP (Siro Mus effector protein) interaction). mTOR is a mammalian serine / threonine kinase of approximately 289 kDa in size, which is a member of the evolutionary conserved eukaryotic TOR kinases (References 1-4). The mTOR protein is a member of the P13-kinase-like protein kinase (PIKK) family because its C-terminus is compatible with P13-kinase and other members of this family, such as DNA-PKc (DNA-dependent prot...
