Procedure

To a solution of 4-{[(3-chloro-2-methylphenyl)methyl]amino}-2-(4-morpholinyl)-1,3-thiazole-5-carboxamide (200 mg, 0.545 mmol) in Tetrahydrofuran (THF) (20001) was added (1S)-2-chloro-1-methyl-2-oxoethyl acetate (164 mg, 1.090 mmol). The mixture was stirred at room temperature overnight, and then stirred at 60° C. for 3 h. To the mixture was added sodium hydroxide (454 μl, 2.73 mmol) and methanol (0.5 mL). After 30 min, the mixture was acidified (pH ˜5) with 6N HCl, and then concentrated. The residue was partitioned between dichloromethane and water. The organic layer was dried (sodium sulfate), filtered, and concentrated. The crude was purified by reversed-phase HPLC and subsequently converted to the HCl salt to provide 4-[(3-chloro-2-methylphenyl)methyl]-5-[(S)-1-hydroxyethyl]-2-(4-morpholinyl)[1,3]thiazolo[4,5-d]pyrimidin-7(4H)-one. (14 mg, 6%); LC/MS: MS (ES+) m/e 421 (MH+); 1H NMR (400 MHz, DMSO-d6) δ ppm 1.34 (d, J=6.3 Hz, 3H), 2.44 (s, 3H), 3.53-3.62 (m, 4H), 3.67 (m, 4H), 4.57 (q, J=6.3 Hz, 1H), 5.67 (s, 2H), 6.51 (d, J=7.8 Hz, 1H), 7.14 (m, 1H), 7.37 (d, J=7.8 Hz, 1H).
