Procedure
10,11-Dihydro-5H-dibenzo[a,d]cycloheptene-5-methylamine (8.5 g) and γ-butyrolactone (3.7 g) are heated at 150° C. (internal temperature) for 1 hour. After cooling, the solid residue is recrystallized from benzene to give N-[(10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl)methyl]-4-hydroxybutyramide, (III, Alk = CH2CH2CH2 and Y = OH), m.p. 103°-105° C.
