Procedure

A mixture of (5-butyl-1-(5-methyl-4-(thiophen-2-yl)pyrimidin-2-yl)-1H-pyrazol-4-yl)methanamine and 2-(1H-imidazol-5-yl)acetic acid in 1:1 molar ratio was treated with EDC (1 equiv.), HOBT (1 equiv.) and N-methylmorpholine (2 equiv.) in methylene chloride (at a concentration of 0.5 M) at room temperature overnight (20 hours). Upon completion, an additional methylene chloride was added and the resulting mixture was washed with water and brine, dried over anhydrous sodium sulfate and concentrated. The crude material was purified by column chromatography using 10% CH3OH/CH2Cl2 as the eluent to give the title compound 34. 1H NMR (400 MHz, CD3OD) δ 8.79 (s 1H), 8.34 (t, J=5.48 Hz, 1H), 8.10 (s 1H), 7.94 (s 1H), 7.93 (s 1H), 7.62 (s 1H), 7.33 (D, J=4.69 Hz, 1H), 7.10 (s 1H), 4.18 (D, J=5.48 Hz, 2H), 3.49 (s 3H), 3.11 (t, J=7.83 Hz, 2H), 2.60 (s 3H), 1.40 (quint, J=7.43 Hz, 2H), 1.24 (sex, J=7.83 Hz, 2H), 0.77 (t, J=7.43 Hz, 3H). LCMS (ES+) m/z 436 (M+1).
