Procedure

To a solution of 7-(heptyloxy)quinoline-3-carbaldehyde (1.6 g, 5.9 mmol) in THF (30 mL) at 0° C. was added CH3MgI (2 g, 12 mmol, 2 eq.) dropwise over 10 min. The mixture was warmed to rt over 8 h. Then, the reaction mixture was quenched (water), extracted (EA), washed (brine), dried (Na2SO4), filtered and evaporated to dryness to give the crude product, which was purified by silica gel column chromatography (PE-EA, 1:5) to give desired compound as yellow oil (1.35 g, yield 80%). ESI-MS: 288 (M+H)+. 1H NMR (300 MHz, CDCl3) δ: 0.90 (t, 3H), 1.32-1.41 (m, 6H), 1.43-1.49 (m, 2H), 1.56-1.58 (d, 2H), 1.78-1.85 (m, 2H), 4.02 (t, 2H), 5.02-5.07 (q, 1H), 7.14-7.17 (m, 1H), 7.36 (s, 1H), 7.60-7.63 (d, 1H), 8.01 (s, 1H), 8.72 (s, 1H).
