Reaktionsschritte
A mixture of 0.1 g of the compound obtained in EXAMPLE 1' in 3 ml of 2-propanol is heated to reflux, 0.022 g of 83% isethionic acid (obtained by elution of sodium isethionate on DOWEX® 50 W×8 resin in H+ form) is added and crystallization is allowed to take place overnight. The crystallized product formed is drained. 0.055 g of the expected product is obtained, m.p.=230° C.
