実験手順
1-(5-bromo-3-(4-fluorophenoxy)pyridin-2-yl)thiourea (3.00 g, 8.77 mmol; prepared according to Example 179, Step D), TEA (2.08 mL, 14.9 mmol) and tert-butyl 4-(2-bromoacetyl)piperidine-1-carboxylate (3.49 g, 11.4 mmol) were refluxed in ethanol (75 mL) for 2 hours. The reaction was cooled to room temperature and filtered to afford the title compound (3.6 g, 74.7% yield).
