Reaction Steps

{4-[2-(4-{{2-[4-(Tetrahydro-furan-2-carbonyl)-piperazin-1-yl]-ethoxy}-benzyl)-pyrimidin-5-yl]-benzylamino]-acetic acid tert-butyl ester can be synthesized by the following procedure. To a solution of (4-{2-[4-(2-chloro-ethoxy)-benzyl]-pyrimidin-5-yl}-benzylamino)-acetic acid tert-butyl ester (0.032 mmol) (from Example 5y) in anhydrous DMF is added sodium iodide (0.0384 mmol) and 1-(tetrahydro-2-furoyl)-piperazine (0.16 mmol). The reaction mixture is heated at 90° C. for 8 h. Purification by preparative LCMS (ACN gradient 10-90%) affords {4-[2-(4-{2-[4-(tetrahydro-furan-2-carbonyl)-piperazin-1-yl]-ethoxy}-benzyl)-pyrimidin-5-yl]-benzylamino}-acetic acid tert-butyl ester (51%). 1H NMR (400 MHz, CDCl3) δ 7.66 (d, J=8.0 Hz, 2H), 7.62 (d, J=8.8 Hz, 1H), 7.58 (d, J=8.8 Hz, 2H), 7.51 (d, J=8.0 Hz, 2H), 7.46 (d, J=7.2 Hz, 1H), 6.85 (d, J=9.2 Hz, 2H), 4.3 (m, 4H), 3.85 (m, 4H), 3.76 (m, 3H), 3.52 (m, 4H), 2.35 (m, 4H), 2.0 (m, 4H), 1.48 (s, 9H).
