Reaction Steps

(S)-ethyl 5-(4-bromophenyl)-2-(1-(tert-butoxycarbonyl)pyrrolidin-2-yl)-1H-imidazole-4-carboxylate (1 g, 2.1 mmol) was dissolved in 2M methylamine in MeOH (35 mL) and heated in a pressure vessel at 70° C. for 48 h. The reaction mixture was concentrated and the residue applied to a Biotage 25 m silica gel cartridge and eluted by 10-100% gradient, ethyl acetate/Hex to give 556 mg (57%). 1H NMR (300 MHz, DMSO-d6) δ 12.5 (br.s, 1H), 7.86-7.82 (m, 1H), 7.77 (d, J=8.4 Hz, 2H), 7.61 (d, J=8.7 Hz, 2H), 4.83-4.70 (m, 1H), 3.69-3.52 (br.s, 1H), 3.42-3.32 (m, 1H), 2.71 (d, 4.8 Hz, 3H), 2.30-1.78 (m, 4H), 1.19-1.14 (m, 9H).
