By replacing the 7-nitro-3'-isopropyl-3,4-dihydro-2H-1,5-benzodioxepin-3-spiro-5'-oxazolidin-2'-one employed in Example 143, Step C, by an equivalent quantity of 7-dimethylamino-3'-isopropyl-3,4-dihydro-2H-1,5-benzodioxepin-3-spiro-5'-oxazolidin-2'-one and following substantially the same procedure described in Example 143, Step C, there is obtained 7-dimethylamino-3-isopropylaminomethyl-3-hydroxy-3,4-dihydro-2H-1,5-benzodioxepin.
