Cyclopropylamine → HCID 54675653, compound

Participants

Reaction Steps

To the intermediate from Step A above (165 mg, 0.367 mmol) was added cyclopropylamine (3.31 mL, 47.7 mmol) and the resultant mixture heated to 50° C. for 16 hours. The reaction mixture was concentrated in vacuo and the residue purified by silica gel column chromatography using a DCM/MeOH (with 0.5% NH4OH) gradient. Chiral separation using SFC on a Chiralcel OJ-H column provided both enantiomers of the title compound. 1H NMR (500 MHz, DMSO-d6): δ 11.23 (1H, s), 9.02 (1H, dd, J=8.08, 1.55 Hz), 8.62 (1H, dd, J=4.50, 1.57 Hz), 7.64 (1H, d, J=4.05 Hz), 7.37 (1H, dd, J=8.08, 4.49 Hz), 6.76 (2H, s), 4.81 (2H, t, J=6.60 Hz), 3.06-2.94 (2H, m), 2.67-2.60 (1H, m), 1.55 (3H, s), 0.62-0.53 (2H, m), 0.50-0.41 (2H, m). m/z=461.3 (M+H).
