To a mixture of ethyl 3-oxo-3-(tetrahydro-2H-pyran-4-yl)propanoate (0.2 g, 0.999 mmol) and 4-{[2-methyl-3-(trifluoromethyl)phenyl]methyl}-1H-pyrazole-3,5-diamine (0.270 g, 0.999 mmol) was added Methanol (4 mL) and hydrochloric acid (0.4 mL, 0.500 mmol) in methanol (1.25 N). The reaction vessel was sealed and heated at 65° C. for 6 days. The reaction mixture was concentrated to 1 mL. The solid was filtered and wash with methanol (2 ml×3) and dried (0.19 g, 45%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.51-1.84 (m, 4H) 2.47 (s, 3H) 2.58-2.75 (m, 1H) 3.34-3.39 (m, 2H) 3.85 (s, 2H) 3.93 (dd, J=11.24, 3.16 Hz, 2H) 5.28 (s, 2H) 5.41 (d, J=1.52 Hz, 1H) 7.01 (d, J=7.83 Hz, 1H) 7.28 (m, 1H) 7.54 (d, J=7.83 Hz, 1H) 11.18 (s, 1H); LC/MS: MS (ES+) m/e 407.2 [M+H]+.
