By a procedure similar to that described in Example 34, 3-methylsulfonyl-11H-s-triazolo[3,4-b][3] benzazepine was reacted with sodium ethoxide/ethanol, in lieu of sodium methoxide/methanol, to obtain 3-ethoxy-11H-s-triazolo[3,4-b][3]benzazepine as crystals. Recrystallization from acetone yielded colorless needles, melting point: 143°-144° C.
