The reaction was run in the same manner as 1-benzoyl-3-piperidinecarbonyl chloride, starting with (S)-1-benzoyl-3-piperidinecarboxylic acid (6.30 g; 27.0 mmols), thionyl chloride (16.06 g, 135 mmol), and dry dichloromethane (150 ml), giving (S)-1-benzoyl-3-piperidinecarbonyl chloride as a light yellow oil, which was used without further purification. MS (in CH3CN) m/z (positive ion) 503 (40), 485 (42), 467 (40), 254 (60), 252 (MH+; 100), 234 (68).
