Reaction Steps

5-(Piperidin-4-ylsulfamoyl)-naphthalene-1-carboxylic acid (2-methyl-cyclohexyl)-amide hydrochloride 48 (190 mg, 0.41 mmol) was dissolved in dichloromethane (1 mL). Triethylamine (0.13 g, 0.18 mL, 1.28 mmol) was added followed by ethyl chloroformate (65 mg, 0.068 mL, 0.60 mmol). The reaction was stirred overnight at room temperature. The crude reaction mixture was charged to a flash column. Elution with 99:1 dichloromethane:methanol afforded H-24 (66 mg, 59%) as a white solid. 1H NMR (300 MHz, CDCl3) (1:1 mixture of diastereomers) δ 8.65 (d, 1H), 8.48 (d, 1H), 8.25 (d, 1H), 7.55 (m, 3H), 6.20 (d, 1H), 5.47 (m, 1H), 5.26 (s, 1H), 4.00 (m, 2H), 3.75 (m, 3H), 3.20 (m, 1H), 2.75 (m, 2H), 2.15 (m, 1H), 1.78 (m 3H), 1.57 (m 2H), 1.38 (m, 2H), 1.05 (m, 10H); LC/MS m/z 502 (M+H)+.
