Reaction Steps

4.8 g of thiopyrano [3,2-b]indol-4(5H)-one and 15 g of chloroethylmorpholine, are reacted in the same manner as described in Example 14, except that the crude free base crystallized. This is filtered and recrystallized from methylenechloride-hexane to give 5.1 g of product, mp 136°-137°C.
