Participants

Reaction Steps

trans-4-(Aminomethyl)cyclohexanecarboxylic acid (10.00 g, 0.06361 mol), in a 10% aq solution of NaOH (5.60 g in 55 mL) was cooled to 0° C. and treated over 15 min with vigorous stirring, with benzyl chloroformate (11 mL, 0.076 mol). After one hour the solution was acidified (1M HCl(aq)) and the resulting the white precipitate collected by filtration, washed with water and hexane then dried in vacuo oven overnight to afford 17.23 g of the title compound. 1H NMR (400 MHz, CDCl3): δ 0.93-0.99 (m, 2H), 1.38-1.46 (m, 2H), 1.82-1.85 (m, 2H), 2.03-2.06 (m, 2H), 2.25 (m, 1H), 3.06 (t, J=5.6 Hz, 2H), 4.83 (m, 1H), 5.09 (s, 2H), 7.31-7.36 (m, 5H). MS (ES+): m/z 292 [MH+].
