Reaction Steps

A mixture of Example 275F (100 mg, 0.275 mmol) in 1.0 mL of N-methylpyrrolidinone was treated with 151 mg of 3-[4-(4-trifluoromethylpyrimidin-2-yl)-piperazin-1-yl]-propylamine and 58 mg of potassium phosphate, warmed to 160° C., stirred for 16 hours, concentrated, and purified by C18 reverse-phase HPLC using acetonitrile/water/0.1% TFA to provide the desired product (63 mg, 36%). MS (ESI) m/e 619 (M+H)+; 1H NMR (400 MHz, CD3OD) δ 8.66 (d, J=4.80 Hz, 1H), 7.52 (dd, J=7.96, 1.51 Hz, 1H), 7.34 (m, 1H), 7.24 (d, J=8.37 Hz, 1H), 7.03 (d, J=4.94 Hz, 1H), 6.97 (d, J=8.37 Hz, 1H), 6.80 (d, J=7.68 Hz, 1H), 6.57-6.61 (m, 1H), 3.75-4.25 (m, 4H), 3.25-3.40 (m, 8H), 2.65-2.76 (m, 4H), 2.03-2.10 (m, 2H), 1.65-1.69 (m, 4H).
