To a solution of (8-benzyl-9,9-dimethyl-11-oxa-3,8-diazaspiro[5.5]undecan-3-yl)-(4-isopropoxy-3-methyl-phenyl)methanone (51 mg, 0.11 mmol) in ethanol (2 mL) was added Pd(OH)2 (16 mg, 0.11 mmol) followed by ammonium formate (29 mg, 0.45 mmol). The reaction mixture was stirred at 40° C. for 18 h, then filtered and concentrated in vacuo to afford (9,9-dimethyl-11-oxa-3,8-diazaspiro[5.5]undecan-3-yl)-(4-isopropoxy-3-methyl-phenyl)methanone (40 mg, 98%). ESI-MS m/z calc. 360.5. found 361.3 (M+1)+; Retention time: 1.29 minutes (3 min run).
