Procedure

HATU (2.70 g, 7.10 mmol) was added to a solution of 4-amino-3-methoxybenzoic acid (880 mg, 5.26 mmol), 3-methoxyazetidine hydrochloride (0.971 g, 7.86 mmol) and DIPEA (2.85 mL, 16.32 mmol) in THF (15 mL) at room temperature. THF was removed under reduced pressure, and the residue partitioned between EtOAc and saturated aqueous NaHCO3. The aqueous layer was extracted with EtOAc and the combined organic layers were washed with brine, dried and concentrated. The residue was purified by silica gel column chromatography eluting with 0 to 100% EtOAc in cyclohexane followed by a second chromatography eluting with 0 to 4% MeOH in DCM to afford the title compound (728 mg, 59%).
