2-Phenyl-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)pyrimidine (Step A, 51 mg) was added to a 1 N hydrochloric acid solution in methanol (5 mL). The solution was stirred at room temperature for two hours. MTBE (40 mL) was added to precipitate a white solid which was filtered and rinsed with MTBE and dried under high vacuum. The title compound was obtained as a white powder (11.4 mg, 27% yield); melting point 264-273° C.; 1H-NMR (300 MHz; CD3OD) δ 10.0 (s, 1H), 9.29 (s, 2H), 8.44 (dd, 2H), 7.86 (d, 1H), 7.54 (m, 3H), 6.95 (d, 1H); MS (ESI+) m/z 223 (M+1); H-PGDS FPBA IC50: 2.4 μM.
