Procedure

A mixture of (1R)-1′-({1-[4-(6-fluoropyridin-3-yl)phenyl]cyclopropyl}carbonyl)-3H-spiro[2-benzofuran-1,3′-pyrrolidin]-3-one (20.0 mg, 0.0000467 mol, see example 250 for the preparation), and ammonium acetate (0.0216 g, 0.000280 mol) in dimethyl sulfoxide (0.5 mL, 0.007 mol) and water(0.1 mL) was heated at 100° C. in a sealed tube overnight. The major product was the phenol rather than the aniline derivative. The product was isolated and purified by prep-HPLC. LC-MS: 427.2 (M+H+)
