58% To a solution of 22 g of the foregoing Intermediate (I-10) dissolved in 60 ml of N,N-dimethylacetoamide, 12.5 g of <strong>[25761-72-2]diallylcarbamoyl chloride</strong> and 15 ml of pyridine were added in this order and they were reacted for 10 hours at 40 C. on a hot water bath. After the completion of reaction, the reaction mixture was poured into a dilute hydrochloric acid. Precipitated crystals were collected by filtration. The crystals were washed with water and dried. These coarse crystals were recrystalized from 200 ml of acetonitrile. The thus-precipitated crystals were collected by filtration. The crystals were washed with acetonitrile and then dried. As a result, 15 g (yield 58%) of the objective exemplified compound (2) was obtained, as a white crystal.

In ethyl acetate; To the refluxing, stirred solution was added dropwise a solution of diallylamine (50 g.) in ethyl acetate (100 ml.), maintaining a brisk flow of phosgene. The rate of addition of the solution of diallylamine was such that solid diallylamine hydrochloride did not accumulate in the reaction mixture. When the addition was complete, the flow of phosgene into the stirred, refluxing reaction mixture was maintained for 30 minutes. The reaction mixture was distilled under reduced pressure to remove the solvent and give the product, diallylcarbamoyl chloride, as an oil, b.p. 67 - 69C./3 mm.

The organic layer and aqueous layer are separated, and the aqueous layer is extracted with ethylether, which extracts are combined with the organic layer. The combined ether extracts and organic layer are washed with 100 milliliters of a 10 weight percent aqueous solution of sodium hydroxide (NaOH), then with 100 milliliters of a 10 weight percent aqueous hydrochloric acid solution, and then dried with sodium sulfate (Na2 SO4) and filtered, and the solvent is removed on a rotary evaporator to give the crude product which can be further refined by crystallization.

The compound containing fractions were concentrated in vacuo and the resulting residue was purified by FCC on silica, using a gradient of 0-6% [2M NH3 in MeOH] in DCM, to afford the title compound (2.30 g, 46%) as a yellow solid. LCMS (Method 1): Rt 2.26 min, m/z 251 [MH+].
