Procedure:
To a flask was added a few drops of N,N-dimethylformamide and 35.25 g of 3-(6,11-dihydro-11-oxodibenz[b,e]oxepin-2-yl)propanoic acid in 500 ml of dry methylene chloride. The chilled stirring suspension was treated dropwise over several minutes with 11.0 ml of thionyl chloride. The suspension was warmed intermittently on a steam bath until all gas evolution ceased. The resulting solution was then allowed to reflux for 15 minutes and was allowed to stand at room temperature under nitrogen atmosphere overnight. The solution was concentrated in vacuo to an oil. The oil was dissolved in 500 ml of methylene chloride and was treated with another 11.0 ml of thionyl chloride. The solution was allowed to reflux for 3 hours and was again concentrated to an oil in vacuo. The oil still contained a significant amount of crystalline impurity, which was filtered away after triturating with a hexane/ether solution. The supernatant was concentrated to an oil in vacuo which solidified overnight in refrigeration. The purified solids were recrystallized from three portions of cyclohexane to give 25.03 g of 3-(6,11-dihydro-11-oxodibenz[b,e]oxepin-2-yl)propanyl chloride, m.p. 69-72° C.

Procedure:
1,4-Butanediol (54 g, 0.60 mol) was placed in a 500 mL 3-necked RB flask and treated with 0.3 mL trimethylsilyl chloride. A portion of HMDS (ca. 20 mL) was added, and an exothermic reaction took place as the mixture became homogeneous. The remainder of the HMDS (120 mL, 0.66 tool total) was added at a controlled rate (ca. 3-5 mL/min), maintaining the reaction temperature at ca. 50° C. Heating was continued at 100° C. (3 h), and 150° C. (1.5 h) GC analysis (method 1) revealed excess HMDS and one product. Distillation provided 127.8 g of colorless oil, bp 97°-99° C./15 mm. 1H NMR (CDCl3): 3.75-3.50 (m, 4H), 1.75-1.50 (m, 4H), 0.16 (s, 18H).

Procedure:
1-(Diphenylmethyl)-3-hydroxyazetidine-3-carboxylic acid (assume 3.90 mmol) was suspended in methanol (40 mL) and 4 N hydrochloric acid in dioxane (1 mL, 4 mmol) was added. 20 wt % Palladium hydroxide on carbon (100 mg) was added to the solution and the mixture was treated with hydrogen at 40 psi for 2 h. The mixture was filtered and the filtrate was concentrated in vacuo to afford 3-hydroxyazetidine-3-carboxylic acid hydrochloride which was dissolved in tetrahydrofuran (5 mL) and water (5 mL) and treated with potassium carbonate (1.615 g, 11.7 mmol) and di-tert-butyl dicarbonate (935 mg, 4.29 mmol) were added. The mixture was stirred at ambient for 17 h and then the mixture was partitioned between ethyl acetate and water. The aqueous portion was extracted with ethyl acetate and then was acidified to pH ˜3-4 and extracted twice more with ethyl acetate. The combined organic portion was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to afford 1-{[(1,1-dimethylethyl)oxy]carbonyl}-3-hydroxyazetidine-3-carboxylic acid which was dissolved in DMF (3 mL). Benzotriazol-1-yloxytris(pyrrolidino)phosphonium hexafluorophosphate (2.028 g, 3.90 mmol) and N,N-diisopropylethylamine (0.7 mL, 4.03 mmol) were added. The mixture was stirred at ambient for 5 minutes and then allylamine (0.6 mL, 8.03 mmol) was added and the mixture was stirred for 17 h. The mixture was partitioned between ethyl acetate and 5% lithium chloride. The organic portion was washed with 20% citric acid, saturated sodium bicarbonate and brine, then was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. Column chromatography (silica gel, ethyl acetate) gave 1,1-dimethylethyl 3-hydroxy-3-[(prop-2-en-1-ylamino)carbonyl]azetidine-1-carboxylate (782 mg, 3.05 mmol, 78% yield from 1-(diphenylmethyl)-3-hydroxyazetidine-3-carboxamide). 1,1-Dimethylethyl 3-hydroxy-3-[(prop-2-en-1-ylamino)carbonyl]azetidine-1-carboxylate (782 mg, 3.05 mmol) was dissolved in methanol (10 mL) and 4 N hydrochloric acid in dioxane (2 mL, 8 mmol) was added. The mixture was refluxed for 15 minutes and then was concentrated in vacuo to afford 3-hydroxy-N-prop-2-en-1-ylazetidine-3-carboxamide hydrochloride (3.05 mmol).

Procedure:
Triethylamine (1.87 g, 18 mmol) was added slowly to a stirred suspension of methyl-3-(aminomethyl)-2-(methoxycarbonyl)benzoate hydrochloride (2.0 g, 8 mmol) in dichloromethane (30 ml). The resulting mixture was cooled in an ice bath to 4° C. Acetyl chloride (0.73 g, 9 mmol) was added dropwise at a rate such that the temperature stayed between 4-7° C. After addition was complete, the mixture was stirred in the ice bath for an additional 30 minutes and then allowed to warm to room temperature and maintained for 2 hours. The reaction mixture was washed with water (2×30 ml), brine (30 ml) and dried. Solvent was removed in vacuo and the product was purified by chromatography (dichloromethane/ethyl acetate 6 to 4) to afford 1.65 g (80%) of the product as an oil: 1H NMR (CDCl3) δ 7.86 (d, J=7.7 Hz, 1H), 7.62 (d, J=7.6 Hz); 7.46 (t, J=7.7 Hz); 6.29 (b, 1H), 4.39 (d, J=6.1 Hz, 2H), 3.93 (s, 3H), 3.90 (s, 3H), 1.96 (s, 3H).
