Diisopropylethylamine → N-[4-(1-Hydroxy-1-methyl-ethyl)-cyclohexylmethyl]-2-(3-nitro-phenoxy)-nicotinamide

Participants

Reaction Steps

A solution of 2-(3-nitro-phenoxy)-nicotinic acid (86.9 mg, 0.33 mmol), trans-2-(4-Aminomethyl-cyclohexyl)-propan-2-ol (57.2 mg, 0.33 mmol), benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (148 mg, 0.33 mmol), and diisopropylethyl amine (0.29 mL, 1.67 mmol) in 10 mL of dry DMF was stirred overnight. The solution was then diluted with ethyl acetate and washed with water, 5% citric acid, saturated sodium bicarbonate, and brine, dried over magnesium sulfate and concentrated to an oil. Purified through a pad of silica eluted with ethyl acetate to give a clear oil (120 mg.) 1HNMR (CDCl3) δ1.04 (4H, dd), 1.14 (6H, s), 1.55 (2 s), 1.88 (4. m), 3.37 (2H, t) 7.23 (1H, m), 7.51 (1H, d), 7.64 (1H, t), 8.07 (1H, t), 8.16 (2H, m), 8.63 (1H, dd); MS: m/e 414 (M++1).
