実験手順

24.4 ml of 37 percent aqueous formaldehyde are added to the stirred suspension of 10.3 g of slow moving 1-(2-isopropylaminopropyl)-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one (Example 1) in 15.7 ml of formic acid. The mixture is refluxed for 8 hours, evaporated and the residue suspended in water. The mixture is basified to pH=10-11 with 3 N aqueous sodium hydroxide and extracted with chloroform. The extract is dried, evaporated, and the residue crystallized from diethylether, to give the 1-[2-(N-isopropyl-N-methylamino)propyl]-3-hydroxymethyl-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one melting at 158°-161°, (R,R-isomer).
