Procedure
To 2-chloro-5-fluoro-4-(3-(4-fluorophenoxy)azetidin-1-yl)pyrimidine (90.0 mg, 0.302 mmol) and 3-amino-N-methylbenzamide (49.9 mg, 0.333 mmol) in a disposable sealed tube in 2-propanol (2.50 mL) was added trifluoroacetic acid (0.070 mL, 0.907 mmol). The resulting reaction mixture was heated at 84° C. for 3 d, cooled to RT and concentrated. The residue was stirred in EtOAc and saturated aqueous NaHCO3 for 10 min and transferred to a reparatory funnel. The organic layer was washed with brine, dried and concentrated giving 3-(5-fluoro-4-(3-(4-fluorophenoxy)azetidin-1-yl)pyrimidin-2-ylamino)-N-methylbenzamide (124.8 mg).
