Reaction Steps

30 g of 4-methoxycaprolactone were stirred at 330° C. for 1 hour together with 100 g of 25% strength aqueous ammonia in the same manner as described in Example 4. After cooling and depressurizing the autoclave and working up the reaction mixture by distillation, 9.1 g of 5-hydroxyethylpyrrolidone were obtained (34%, based on the 4-methoxycaprolactone employed) and identified by NMR spectroscopy.
