실험 절차

Trans-4-Amino-cyclohexanecarboxylic acid methyl ester (2.14 g, 11.05 mmol) is suspended in THF (50 mL) and Et3N (2.79 g, 27.6 mmol) and cooled to 0° C. 5-chloro-2-methylnicotinoyl chloride (step 1)(2.20 g, 11.05 mmol) is slowly added portionwise and the RM is stirred at r.t. for 2 hours. LCMS showed mainly product. The reaction mixture is partitioned between EtOAc and 1M HCl. The organic phase is washed with water and brine, dried over MgSO4, filtered and the solvent is removed in vacuo to afford the title product which is used in the next step without further purification. 1H NMR (400 MHz, DMSO-d6) δ 8.53 (1H, d), 7.42 (1H, 5), 7.80 (1H, d), 3.70 (1H, m), 3.60 (3H, s), 2.49 (3H, s), 2.29 (1H, m), 1.95 (4H, m), 1.42 (2H, m), 1.29 (2H, m); [MH]+ 311.26.
