Reaction Steps

4-(3-Dimethylamino-2-methyl-acryloyl)-1H-pyrrole-2-carboxylic acid (2-hydroxy-1-phenyl-ethyl)-amide (100 mg, 0.29 mmol) was combined with cyclopropyl guanidine.HCl (80 mg) and potassium carbonate (121 mg) in N,N-dimethylacetamide (2 mL). The resulting suspension was heated and stirred at 100° C. for 24 hours. The crude material was diluted with ethyl acetate, washed with saturated NaHCO3 and brine, dried over MgSO4 then concentrated in vacuo. Purification by preparative TLC (silica, 1:1 EtOAc:Hexanes) afforded III-a-162 as a yellow solid (7.8 mg). HPLC Method B, Rt=4.29 minutes; LC/MS(m/z) 378.2 (M+1), 376.2 (M−1); 1H NMR consistent with structure.
