The title compound was prepared by a method analogous to that described for Intermediate 44, using 2,2-difluoroethylamine instead of 2,2,2-trifluoroethylamine. +ESI (M+H) 267.2; 1H NMR (400 MHz, DMSO-d6, δ): 1.63 (t, J=19.02 Hz, 3H) 3.89-3.99 (m, 2H) 6.97 (d, J=8.97 Hz, 1H) 7.54 (t, 1H) 7.62-7.68 (m, 1H) 7.71 (d, J=8.19 Hz, 1H) 7.96 (d, J=9.10 Hz, 1H) 8.06-8.09 (m, 1H) 12.95 (bs, 1H).
