[0287] Preparation of the compounds of the invention
[0288] Another aspect of the present invention provides a method for preparing a compound of formula (I) or a pharmaceutically acceptable salt thereof, the method comprising:
[0289] Method a-1) The amine of formula (A)
[0290]
[0291] React with the acid of formula B or its activated acid derivative:
[0292]
[0293] Method a-2) The amine of formula (A)
[0294]
[0295] React with R-N=C=O, where R is C 1-6 Alkyl, aryl, aralkyl, heteroaralkyl or heteroaryl;
[0296] Method a-3) The amine of formula (A)
[0297]
[0298] React with chloroformate or activator (such as carbonyl diimidazole, phosgene or other reagents known to the skilled person), then react with ROH or RR’NH, where R is C 1-6 Alkyl, aryl, heteroaryl, aralkyl or heteroaralkyl and R’ is H or C 1-6 alkyl;
[0299] Method b) The acid of formula C or its activated acid derivative:

[0506] 5-{[3-(1-cyano-1-methylethyl)benzoyl]amino}-2-methyl-N-(2-methyl-1,3- Thiazol-5-yl)benzamide
[0507] At room temperature, add 5-{[3-(1-cyano-1-methylethyl)benzoyl]amino}-2-methylbenzoic acid (Method 7, 82mg, 0.25mmol), 2-methyl -1,3-thiazol-5-amine (Method 2, 28mg, 0.25mmol), HATU (101mg, 0.275mmol) and N,N-diisopropylethylamine (0.135mL) in DMF (0.5mL) The solution was stirred for 16 hours. The reaction mixture was partitioned between water and EtOAc, the organic layer was washed with brine and then dried (MgSO 4 ). Purified by reverse phase HPLC (5%-95% water-MeCN, 15 minutes), after solvent evaporation, 51 mg (48%) of the title compound was obtained.

Embodiment 2-24
[0510] By a method similar to Example 1, using 1,3-thiazol-5-amine (method 1), 2-methyl-1,3-thiazol-5-amine (method 2), 5-amino-N-methyl Yl-1,3-thiazole-2-carboxamide (method 3), 2-(morpholin-4-ylcarbonyl)-1,3-thiazol-5-amine (method 4), 5-amino-N-methyl Oxy-N-methyl-1,3-thiazole-2-carboxamide (Method 5), 2-isopropyl-1,3-thiazol-5-amine (Method 33) or 2-cyclopropyl-1 , 3-thiazol-5-amine (Method 34) and appropriate starting materials to prepare the following compounds. In some cases, alternative purification methods (column chromatography or recrystallization from EtOAc:hexane) are required.
