Reaction Steps

L-Cysteine hydrochloride (78.5 g) is added to 150 ml of hexanol saturated with dry HCl gas. The mixture is heated under reflux overnight. The solution is evaporated to about half of the total volume, and then ethyl ether (150 ml) is added. The solution gives crystals when it is cooled. The crystals are filtered and are then recrystallized from ethyl acetate; yield 45 g; mp 89°-90° C.; IR (KBr) 1745 cm-1 ; NMR (CDCl3) δ9.2-8.4 (b, 3, NH3⊕), 4.7 (t, 1, --CH--), 4.3 (t, 2, --OCH2 --), 3.4 (b, 2, CH2S--), 1.0-3.0 (m, 8), 1.0 (t, 3--, CH3).
