Methylamine → HCID 53473322, compound

Participants

Reaction Steps

To a solution of methylamine (11 mg, 0.11 mmol) and CDI (20 mg, 0.13 mmol) in anhydrous CH2Cl2 (3 mL) was added DIEA (130 mg, 1.00 mmol) at 0° C. under nitrogen. The resulting mixture was stirred at ambient temperature for 1 h. (R)-6-(2-aminoethyl)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one (40 mg, 0.088 mmol) was added to the above mixture, and the mixture was stirred at rt overnight. The mixture was concentrated in vacuo to give a residue, which was purified by preparative HPLC to afford 1-(2-((R)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)ethyl)-3-methylurea (5 mg, 12%). 1H NMR (CDCl3): 1.56 (m, 3H), 2.10-2.30 (m, 4H), 2.35 (m, 1H), 2.75 (s, 3H), 3.01 (m, 1H), 3.09 (m, 1H), 3.30 (m, 1H), 5.69 (m, 1H), 6.86-6.96 (m, 2H), 7.08 (m, 4H), 7.25 (m, 2H), 7.30 (m, 3H).
