Diisopropylethylamine → HCID 22258331, compound

Participants

Reaction Steps

1-Cyclopropylmethyl-6-fluoro-1,2,3,4-tetrahydro-naphthalen-2-ylamine hydrochloride (127 mg, 0.49 mmol), isoquinolin-5-yl-carbamic acid phenyl ester (150 mg, 0.49 mmol), and diisopropylethylamine (193 mg, 1.47 mmol) were combined and stirred at ambient temperature in DMSO (3 mL) overnight. The product was purified by directly injecting the crude reaction onto a reverse phase prep-HPLC (10-90% water:acetonitrile gradient). The appropriate fractions were lyophilized to yield 1-(1-cyclopropylmethyl-6-fluoro-1,2,3,4-tetrahydro-naphthalen-2-yl)-3-isoquinolin-5-yl-urea 71 (68 mg, 0.14 mmol). MS (MH+) 390; 1H NMR (CD3OD) δ 0.08-0.87 (m, 2H), 1.60-1.65 (m, 2H), 2.03 (m, 1H), 2.97 (m, 2H), 3.14 (m, 1H), 4.36 (m, 1H), 6.87 (m, 2H), 7.27 (m, 1H), 7.93 (t, 1H, J=2.6 Hz), 8.14 (d, 1H, J=2.7 Hz), 8.32 (d, 1H, J=2.2 Hz), 8.47 (d, 1H, J=2.6 Hz), 8.53 (d, 1H, J=2.2 Hz), 9.63 (s, 1H). HPLC Rt=3.63 min (10-90% water:acetonitrile gradient, 100% pure).
