Reaction Steps

Thionyl chloride (2.55 mL, 35 mmol) was added dropwise to absolute ethanol (100 mL) under a N2 atmosphere. The resulting solution was stirred at room temperature for 10 min then 4-amino-1-cyclohexanecarboxylic acid (4.29 g, 30 mmol, cis, trans mixture) was added as a solid. The resulting solution was stirred at room temperature overnight. The solvent was removed in vacuo, the residue dissolved in ethanol (25 mL) and this solution was slowly added to a flask containing rapidly stirred ether (700 mL). The precipitate that formed was collected by filtration and dried in vacuo to give 5.75 g, 92% as a white solid. MS (ion spray) 172 (M+1).
