Reaction Steps

Ethyl 5-ethyl-2-oxazoline-4-carboxylate (10.3 g), water (1.62 ml) and triethylamine (0.086 ml) were stirred at 100° C. for 3 hours. To this mixture was added 5N HCl (26 ml) and the mixture diluted to 100 ml with water, washed twice with methylene chloride and brought to pH 10 with 50% sodium hydroxide solution. The solution was extracted with methylene chloride (6 × 30 ml), dried and evaporated to yield the racemic title compound (e11) (9.4 g).
