Procedure

N-methylmorpholine (0.25 mL, 2.27 mmol) was added to a suspension of 2-chloro-4,6-dimethoxy-1,3,5-triazine (405 mg, 2.27 mmol) and 2-{2-[(tert-butoxy) carbonylamino]-2-methylpropanoylamino}-2-phenylacetic acid (570 mg, 1.69 mmol) in CH2Cl2 (7 mL) and THF (2 mL) at 23° C. The mixture stirred for 2 h and 2-(4-aminoimidazolyl)-2-phenyl-1-pyrrolidinylethan-1-one dihydrochloride (779 mg, 2.27 mmol) was added in one portion. After 16 h, the reaction was diluted with EtOAc (50 mL) and 10% (w/w) aqueous citric acid. The phases were separated, and the organic layer was washed with 20 mL each of saturated aqueous NaHCO3 and saturated aqueous NaCl, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by flash chromatography (gradient 2/98 to 6/94 MeOH/CH2Cl2) to give 405 mg (40%) of the title compound. 1H NMR (CDCl3, 300 MHz) d 10.61 (m, 1H), 7.75 (s, 1H), 7.45-7.15 (s, 12H), 5.95 (s, 1H), 5.80 (m, 1H), 3.60-3.38 (m, 3H), 3.10 (m, 1H), 2.15 (m, 1H), 1.98-1.65 (m, 3H), 1.50-1.05 (m, 15H); IR (CHCl3) 3400, 3000, 1706, 1661, 1486, 1455, 1157 cm−1; MS (electrospray) m/z 588 (M+H), 589 (M−H), 587.
