Procedure
NR2=Pyrrolidine (11f). The HCl salt of 11f was prepared by suspending the free base in EtOAc and adding 1.1 eq HCl/Et2O and stirring for 1 h. Filtration of the resulting solid led to a hygroscopic solid. Yield=72%; 1H NMR (CDCl3) δ 7.93 (d, 1H), 7.79 (d, 1H), 7.49 (t, 1H), 7.22 (d, 2H), 7.11 (d, 2H), 4.50 (m, 5H), 4.17 (s, 2H), 3.40 (m, 2H), 3.25 (m, 4H), 3.13 (m, 2H), 2.99 (m, 2H), 2.00 (m, 2H), 1.83 (m, 2H); MS (ES+=375.38). Anal Calcd. for C23H27ClN4O1 (4 H2O): C, 57.19; H, 7.30; N, 11.60. Found: C, 56.93; H, 7.46; N, 11.74.
