Participants

Reaction Steps

Triethylamine (272 mL) was added dropwise to a suspension of methyl cis-4-amino-1-cyclohexane carboxylate hydrochloride (7) (151 g, 0.78 mol) and 2-methylpropane-2-sulfinyl chloride (3) (120.8 g, 1.1 eq) in ethyl acetate (755 mL) at 6 to 9° C. The mixture was stirred for an hour at the same temperature and poured into diluted hydrochloric acid. The mixture was extracted with ethyl acetate (750 mL×2) and each of organic layers was washed with water, 5% aqueous solution of sodium bicarbonate, water and brine, successively. The solvent was concentrated under reduced pressure to obtain oily (14) (222.7 g, 109%).
