Reaction Steps

tert-Butyl-[3-(2-chloro-pyrimidin-4-yl)-benzyl]-carbamic acid allyl ester was coupled with 4-(2-amino-ethyl)-2-chloro-phenol hydrobromide salt (intermediate 71) following procedure F to give the title product in 79% yield. LC-MS showed the product had the expected M+H+ of 495. 1H NMR (Varian 300 MHz, CDCl3, shifts relative to the solvent peak at 7.24 ppm) 8.3 (d, 1H)) 7.9 (m, 2H) 7.4 (m, 1H) 7.3 (m, 1H) 7.2 (s, 1H) 7.0 (d, 1H) 6.9 (m, 2H) 5.9 (m, 1H) 5.2 (m, 2H) 5.1 (m, 2H) 4.7 (s, 2H) 4.6 (d, 2H) 3.7 (m, 2H) 2.9 (m, 2H) 1.41 (s, 9H).
