Procedure

[3-(5-amino-3-t-butyl-pyrazol-1-yl)naphthalen-1-yl]acetic acid ethyl ester hydrochloride (see WO 2006/071940, 1.60 g, 4.55 mmol) was treated with ammonia in methanol (7 M, 13 mL, 91 mmol) and the reaction mixture was heated in a sealed tube for 6 days. The solvent was removed in vacuo and the residue was chromatographed to provide 2-(3-(5-amino-3-tert-butyl-1H-pyrazol-1-yl)naphthalen-1-yl)acetamide (610 mg, 41% yield). MS (ESI) m/z: 323.3 (M+H+).
