Reaction Conditions

Reaction Steps

A mixture of the 3-amino-4-cyclopentyl-1-(4-phenoxyphenyl)-1H-2-pyrrolecarbonitrile (185 mg, 0.539 mmol) in absolute ethanol (10 mL) was treated with formamidine acetate (450 mg, 4.33 mmol) then heated at 85° C. for 2 hours. The solvent was evaporated under reduced pressure then the residue was purified by preparative reverse phase HPLC to provide 145 mg (73%) of the title compound as a white solid after lyophilization: 1H NMR (DMSO-d6, 400 MHz) δ 8.19 (s, 1H), 7.44 (m, 5H), 7.19 (t, 1H), 7.13 (m, 4H), 5.79 (bs, 2H), 3.23 (m, 1H), 2.05 (m, 2H), 1.77 (m, 4H), 1.64 (m, 2H); RP-HPLC (Hypersil HS-C18, 5 μm, 100 A, 4.6×250 mm; 5%–100% acetonitrile-0.05 M ammonium acetate over 25 min, 1 mL/min) tr 23.3 min.; MS: MH+ 371.5.
