Reaction Steps

2-Naphthylamine and ethyl 4,6-dichloronicotinate were reacted in a mixture of EtOH and conc. HCl as for example 33, step A. The resultant solid was isolated by filtration and washed with 10% Et2O/Hexane, yielding ethyl 6-chloro-4-(2-naphthylamino)nicotinate (68%). 1H NMR [400 MHz, (CD3)2SO] δ 9.91 (br s, 1H), 8.71 (s, 1H), 8.02 (d, J=8.7 Hz, 1H), 7.97-7.88 (m, 3H), 7.59-7.48 (m, 3H), 6.91 (s, 1H), 4.39 (q, J=7.1 Hz, 2H), 1.37 (t, J=7.1 Hz, 3H).
