Procedure
A suspension of 4,5-dihydro-3-(1,3,4,9-tetrahydro-1-methyl pyrano[3,4-b]indol-1-yl]-2(3H)-furanone (described in Example 1, 20 g, 0.073 mole) in liquid ammonia is heated at 90° C. in a pressure apparatus for three hours. The apparatus is rinsed with ethanol and the yellow solution is evaporated. The residue is crystallized from ethanol to afford α-(2-hydroxyethyl)-1-methyl-1,3,4,9-tetrahydropyrano[ 3,4-b]-indole-1-acetamide (16.15 g) , m.p. 159°-161° C.
