Embodiment approach
[0084] One embodiment of the present invention is a compound of formula (I) or its stereoisomer, enantiomer or tautomer, its pharmaceutically acceptable salt, its pharmaceutical composition or its prodrug:
[0085]
[0086] X is CH or N;
[0087] Y is NH, N-CH 3 O or S;
[0088] W is selected from -N(R 5 )C(O)-, -C(O)N(R 5 )-, -OC(O)N(R 5 )-, -N(R 5 )C(O)O-, -N(R 5 )C(O)N(R 5 )-, -O-, -S-, -N(R 5 )-, -S(O) t -, -N(R 5 )S(O)t -, -S(O) t N(R 5 )-, -OS(O) t N(R 5 )-, -C(O)-, -OC(O)-, -C(O)O-, -N(R 5 )C(=N(R 5a ))NR 5 -, -N(R 5 )((R 5a )N=)C-,-C(=N(R 5a ))N(R 5 )- or straight key;
[0089] V is selected from -N(R 5 )C(O)-, -C(O)N(R 5 )-, -OC(O)N(R 5 )-, -N(R 5 )C(O)O-, -N(R 5 )C(O)N(R 5 )-, -O-, -S-, -N(R 5 )-, -S(O) t -, -N(R 5 )S(O) t -, -S(O) t N(R 5 )-, -OS(O) t N(R 5 )-, -C(O)-, -OC(O)-, -C(O)O-, -N(R 5 )C(=N(R 5a ))NR 5 -, -N(R 5 )((R 5a )N=)C-,-C(=N(R 5a ))N(R 5 )-,=C(R 5 )- or straight key;

Embodiment 1
[0318] Synthesis of N-benzyl-4-methyl-2-(2-oxopyrrolidin-1-yl)thiazole-5-carboxamide
[0319]
[0320] To N-benzyl-2-(4-bromobutyrylamino)-4-methylthiazole-5-carboxamide (1.80 g, 4.54 mmol) in acetone (50 mL) and water (5 mL) at ambient temperature Potassium carbonate (1.50 g, 10.8 mmol) was added to the solution. The resulting reaction mixture was stirred at ambient temperature for 2 hours. The solvent was removed in vacuo and the residue was washed with water and tert-butyl methyl ether to afford the title compound in 78% yield (1.12 g): mp 222-224°C;
[0321] 1 H NMR (300MHz, DMSO-d 6 )δ8.60(t, J=6.0Hz, 1H), 7.33-7.16(m, 5H), 4.35(d, J=6.0Hz, 2H), 3.97(t, J=7.2Hz, 2H), 2.59( t, J=7.8Hz, 2H), 2.46(s, 3H), 2.14-1.94(m, 2H); MS(ES+) m / z 316.4(M+1).
Embodiment 11
[0323] Synthesis of N-(4-fluorobenzyl)-4-methyl-2-(2-oxopyrrolidin-1-yl)thiazole-5-carboxamide
[0324]
[0325] The procedure was followed as described in Example 1, with modifications as appropriate to use 2-(4-bromobutyrylamino)-N-(4-fluorobenzyl)-4-methylthiazole-5-carboxamide in place of N -Benzyl-2-(4-bromobutyrylamino)-4-methylthiazole-5-carboxamide, the title compound was obtained as a white solid in 85% yield:
[0326] 1 H NMR (300MHz, CD 3 OD) δ7.39-7.33(m, 2H), 7.09-7.02(m, 2H), 4.48(s, 2H), 4.15-4.09(m, 2H), 2.68(t, J=8.1Hz, 2H), 2.55(s, 3H), 2.25(m, 2H); MS(ES+) m / z 334.2(M+1).
