Reaction Steps

To a solution of tert-butyl 4-(4-((4-(2-amino-2-oxoethyl)phenyl)amino)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)piperazine-1-carboxylate in methanol (3 mL) was added HCl (6 M, 0.1 mL). The mixture was heated to 65° C. for 16 h. The Boc group was removed, however, the amide function was replaced with a methyl ester group. The mixture was concentrated and following general procedure C, desired product was obtained after forming the hydrochloride salt (0.015 g, 50%) as an orange-brown solid. MW=424.37. 1H NMR (DMSO-d6, 500 MHz) δ 13.26 (s, 1H), 9.40-9.28 (m, 3H), 7.53 (s, 1H), 7.34 (d, J=8.5 Hz, 2H), 7.29 (d, J=8.5 Hz, 2H), 6.91 (s, 1H), 6.07 (s, 1H), 3.64-3.57 (m, 4H), 3.41 (s, 2H), 3.20 (br s, 4H), 3.02 (t, J=7.5 Hz, 2H), 2.78 (t, J=7.5 Hz, 2H), 2.15 (quin, J=7.5 Hz, 2H); APCI MS m/z, 352 [M+H]+.
