Procedure

A mixture of the products of Example 364D (3.05 g, 5.16 mmol) and Example 8E (N′-(3-cyano-6-isopropyl-pyridin-2-yl)-N,N-dimethyl-formamidine) (1.34 g, 6.20 mmol, 1.2 equiv.) in 25 mL of glacial acetic acid was heated in a 140° C. preheated oil bath for 45 minutes. The reaction mixture was cooled, evaporated in vacuo and the residue partitioned between ethyl acetate (250 mL) and water (100 mL). The organic phase was then washed with saturated aqueous sodium bicarbonate and then brine, dried over anhydrous magnesium sulfate, filtered, and evaporated under reduced pressure. The resulting residue was triturated with methanol, filtered, and dried in vacuo to provide the title compound (3.10 g, 79%) as a beige solid. MS (ESI+) m/z 762/764 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ ppm: 1.33 (d, J=6.99 Hz, 6 H), 3.16-3.26 (m, 1 H), 4.97 (s, 2 H), 6.96 (s, 1 H), 7.43 (d, J=8.82 Hz, 2 H), 7.59 (s, 2 H), 7.86 (s, 1 H), 8.01-8.10 (m, 3 H), 8.15-8.20 (m, 1 H), 8.50 (d, J=2.57 Hz, 1 H), 8.57 (s, 1 H), 8.84 (s, 1 H), 10.23 (s, 1 H), 10.40 (s, 1 H), 10.94 (s, 1 H).
