Reaction Conditions

Reaction Steps

A solution of 67 mg (0.16 mmol) of (R/S)-1-(4-nonylbenzyl)-pyrrolidin-3-ylphosphonic acid, diethyl ester (from Step C) in 1 mL of acetonitrile was treated with 0.094 mL (0.71 mmol) of bromotrimethylsilane. The reaction was allowed to stir at 80° C. for 1 h. The reaction was quenched with MeOH and concentrated several times from MeOH. The residue was purified by LC-2 to afford 27 mg (46%) of the title compound: ESI-MS 368 (M+H); LC-1: 3.1 min.
