Versuchsvorschrift

To a stirred solution of the product from step (iv) above (1 g, 3.13 mmol) and tert-butyl(4-((2-chloropyrimidin-4-yl)oxy)naphthalen-1-yl)carbamate (see, for example, Ito, K. et al., WO 2010/067130, 17 Jun. 2010; 777 mg, 2.090 mmol) in DMF (60 mL) was added pTSA monohydrate (200 mg, 1.051 mmol). The resulting solution was stirred at 60° C. for 72 h. The reaction was cooled to rt, then partitioned between EtOAc (150 mL) and sat. aq. NaHCO3 (100 mL). The aqueous layer was further extracted with EtOAc (2×150 mL), then the combined organic extracts were washed with water (3×200 mL) and brine (200 mL), before being dried (MgSO4), filtered and concentrated to afford an orange oil (1.17 g). The crude product was purified by chromatography on silica gel (80 g column, 0-5% MeOH in EtOAc) to afford the sub-title compound (552 mg) as a light brown foam.
