(3-Diethylamino-pyrrolidin-1-yl)-[3,5-dimethyl-1-[3-(3-methyl-but-1-ynyl)-phenyl]-1H-pyrazol-4-yl}-methanone → (3-Diethylamino-pyrrolidin-1-yl)-[3,5-dimethyl-1-[3-(3-methyl-butyl)-phenyl]-1H-pyrazol-4-yl}-methanone

Participants

Reaction Steps

A suspension of 0.041 g (0.10 mmol) of (3-diethylamino-pyrrolidin-1-yl)-{3,5-dimethyl-1-[3-(3-methyl-but-1-ynyl)-phenyl]-1H-pyrazol-4-yl}-methanone (Example 361) and 6 mg of platinum(IV) oxide hydrate in 0.2 ml of EtOH was stirred under hydrogen atmosphere 17 h at RT and 1 atm. The suspension was filtered and evaporated to give 0.038 g (93%) of the titled compound as colorless viscous oil. MS: 411.2 (MH+).
