(16.5 mmole) of triethylamine in 12 ml. of absolute ethanol was added, at room temperature and under nitrogen, a solution of 0.605 g. mmole) of allyl bromide. After the addition had been completed the reaction mixture was refluxed for eighteen hours and then evaporated to dryness. The residue was mixed 'with a aqueous sodium carbonate solution and the resulting mixture extracted with several portions of ether.
- Example 28 N-allyl-3,l4-dihydroxymorphinan (XXIX).--To a solution of 3.814 g. (12.135 mmole) of XXVIII in 90 ml. of dry CH Cl at -80 C. was added under N dropwise a solution of 9.4252 g. (37.42 mmole) of BBr of 20 ml. of dry CH Cl The resulting reaction mixture was allowed to Warm up to room temperature slowly for 18 hours. It was decomposed with ice-water and the layers separated, the CH CI solution washed with water and saturated NaCl solution. It was dried and evaporated to give 3.76 g. of an oil. This was converted to its HCl salt in acetone.

- l-3,14- dihydroxy-N-cyclopropylmethylmorphinan (XIXa) dl- 3,14 dihydroxy-N-cyclopropylmethylmorphinan (7.835 g., 25 mmole) as the free base was dissolved in 15 ml. of hot methanol. To this was added a solution of 3.75 g. (25 mmole) of l-tartaric acid in 15 ml. of hot methanol. The resulting solution was diluted with 30 ml. of acetone and let stand at 5 C. for 60 hours to crystallize. It was filtered to yield 3.2 g. of a crystalline solid (A). The mother liquor was evaporated to dryness and was made basic with aqueous ammonia to give approximately 5.0 g. of free base (B).
