Versuchsvorschrift

A solution of 2-[3-(1-methyl-1H-pyrazol-4-yl)phenyl]-5-(1H-pyrazol-4-yl)pyrimidine (example 3, 130 mg; 0.43 mmol; 1.0 eq.) in dry DMF (1 mL) was added over a suspension of NaH (60% in oil, 21 mg; 0.86 mmol; 2.0 eq.) in dry DMF (1 mL) maintained at 0° C. under nitrogen atmosphere. The resulting mixture was stirred for one hour at 0° C. then heated at 100° C. O/N after the addition of a solution of 1-chloro-3-methoxypropane (47 mg; 0.43 mmol; 1.0 eq.) in DMF (2 mL). Reaction mixture was then cooled down to RT, quenched with water and extracted with EtOAc (three times). Combined organic phases were washed with water, brine, dried over magnesium sulfate, filtered and concentrated. The resulting solid was dried O/N at 60° C. under reduced pressure to give the title compound a beige powder (165 mg; 75%). 1H NMR (300 MHz, DMSO-d6) δ 9.16 (s, 2H), 8.58-8.49 (m, 1H), 8.46 (s, 1H), 8.30-8.17 (m, 2H), 8.17-8.11 (m, 1H), 7.96-7.89 (m, 1H), 7.75-7.68 (m, 1H), 7.51 (t, J=7.8 Hz, 1H), 4.22 (t, J=7.0 Hz, 2H), 3.90 (s, 3H), 3.39-3.30 (m, 2H), 3.25 (s, 3H), 2.15-1.97 (m, 2H). HPLC (Condition A): Rt 3.34 min (purity 97.1%). MS (ESI+): 375.5.
