Benzene → HCID 21449915, compound

Participants

Reaction Steps

15.43 g (0.2 mol) of cysteamine and 29.0 g (0.2 mol) of isopropyl methyl ketone were treated with 200 ml of benzene and boiled under an inert gas atmosphere for 14 hours on a water-separator. The solution was concentrated on a rotary evaporator and filtered over 25 g of neutral aluminium oxide (activity I). The aluminium oxide was then flushed with ether. The filtrate was again concentrated and subsequently distilled under a high vacuum through a Widmer column. 22.51 g (yield 77% of theory) of 2-isopropyl-2-methyl-thiazolidine (nD20 = 1.5085) passed over in a boiling range of 40°-42° C and at a pressure of 0.009 mm Hg. IR: νmax = 1440, 1370, 790 cm-1. Odour: camphorous, woody; flavour: greenish.
