Procedure
A mixture of tert-butyl(4-chloro-5-cyanopyridin-2-yl)carbamate (intermediate 288, 9.8 g, 38.6 mmol), 2-methoxyethylamine (5.8 g, 77.3 mmol) and DIPEA (6 g, 46.4 mmol) in DMSO (80 ml) was heated at 65-70° C. for 24 h and monitored by chromatography until complete conversion. The solution was then cooled to room temperature and a white solid precipitated gradually. Water (20 ml) was then added slowly within 1 h. The suspension was stirred for a further 1 h, filtered and dried to give the title compound as a white solid. 1H NMR (DMSO-d6, 400 MHz): δ 9.87 (s, 1H), 8.18 (s, 1H), 7.20 (s, 1H), 6.86 (s, 9H), 3.51 (t, 2H), 3.36 (t, 2H), 3.28 (s, 3H), 1.47 (s, 9H).
