The title compound was prepared following procedure described in example 23, step b) from methyl 5-({4-[(4-butylphenyl)ethynyl]benzyl}amino)-2-fluorobenzoate (326 mg; 0.78 mmol) and cyclopropanecarboxaldehyde (Aldrich, 87.94 μl; 1.18 mmol). Purification of the crude by preparative HPLC using a X-Terra column gave 200 mg (54%) of the title compound as a beige oil. HPLC, Rt: 5.91 min (purity: 99.7%), LC/MS, M+(ESI): 470.4, 1H NMR (CDCl3) δ: 7.66 (m, 1H), 7.39 (d, J=7.9 Hz, 4H), 7.00-7.17 (m, 6H), 4.62 (s, 2H), 3.93 (s, 3H), 3.44 (m, 3H), 2.59 (t, J=7.7 Hz, 2H), 1.57 (m, 2H), 1.31 (m, 2H), 0.90 (t, J=7.2 Hz, 3H), 0.53 (d, J=7.2 Hz, 2H), 0.24 (m, 2H).
