The reaction mixture was left at r.t. for 16 h, then diluted with CH2C12 (50 mL) and sequentially washed with sat. NH4C1 solution (15 mL), sat. NaHCO3 solution (3 x 15 mL) and brine (15 mL). The organic layer was dried over Na2SO4, filtered and concentrated to dryness giving a grey oily residue (0.51 g), as a mixture (1:1.5 ratio) of 4-(2-pyridyl)-butyl-2-pyridyl carbonate and 4-(2-pyridyl)-butyl-2-oxopyridine-1-carboxylate. The mixture of isomers was not separated and used in the next step without any further purification. R = 1.64. MS (ESI) mlz: 273 [M-H], 295 [M-Na], 311 [M-K] MS (ESI) mlz: 271 [M-H]

The reaction mixture was stirred at room temperature for 16 h, then diluted with CH2Cl2(20 mL) and sequentially washed with sat. NH4Cl solution (25 mL), sat. NaHCO3 solution (3 x 25 mL)and brine (25 mL). The organic layer was dried over Na2SO4, filtered and concentrated to dryness atlow pressure, as a mixture of alkyl-2-pyridyl carbonate 12b?am and alkyl-2-oxopyridine-1-carboxylate13b?am. The mixture of isomers was not separated and used in the next step without any furtherpurification.

0.02 g General procedure: Under nitrogen atmosphere, to asuspension of 14-21 (1.0 eq.) in dry CH2Cl2 (2.0 mL), DIPEA (1.2 eq.) was added dropwise.Subsequently, the crude mixture containing the corresponding alkyl-2-oxopyridine-1-carboxylate (1.2eq.) in dry CH2Cl2 (4.0 mL) was added. The reaction mixture was stirred at room temperature for 16 h,diluted with CH2Cl2 (10 mL), washed with sat. NH4Cl solution (2 x 20mL), sat. NaHCO3 solution (2 x20 mL), and the organic layer dried over Na2SO4 and concentrated to dryness. Purification wasperformed either by typical silica gel flash chromatography or preparative HPLC affording the desired-lactam carbamates.

YieldReaction ConditionsOperation in experiment
2.14 g With lithium aluminium tetrahydride; In diethyl ether; at 5 - 20℃; for 5h;Inert atmosphere; In a nitrogen atmosphere, aluminum lithium hydride (0.90 g, 23.7 mmol) and dry ether (20 mL) were put in a 200-mL flask, and stirred at 5 C. in an iced water bath. A dry ether (10 mL) solution of the crude product of methyl 4-(2-pyridyl)butyrate (5.17 g, 28.8 mmol) was dropwise added thereto at 10 C. or lower, and stirred at the same temperature for 2 hours. Further, this was heated up to room temperature and stirred for 3 hours. A saturated aqueous Rochelle salt solution (100 mL) and ether (20 mL) were added thereto, stirred overnight, and the organic layer was separated. The aqueous layer was extracted with ether (100 mL), and the combined organic layers were washed with 20% saline water (100 mL), dried with sodium sulfate and concentrated to give a crude product (3.98 g). This was distilled under reduced pressure to give 2.14 g (2-stage yield 44.8%, purity 95.8%) of 2-pyridine-butanol.

YieldReaction ConditionsOperation in experiment
43.4% 60percent sodium hydride (0.47 g, 11.8 mmol) and dry tetrahydrofuran (5 mL) were put into a 200-mL flask, and stirred in a nitrogen atmosphere. In a water bath, a dry tetrahydrofuran (5 mL) solution of 2-pyridine-butanol (1.50 g, 9.92 mmol) was dropwise added thereto at 25° C. or lower, taking 5 minutes, and then stirred at room temperature for 20 minutes. The reactor was again put in a water bath, and a dry tetrahydrofuran (5 mL) solution of benzyl chloride (1.51 g, 11.9 mmol) was dropwise added thereto at 25° C. or lower, taking 15 minutes, and stirred overnight at room temperature. Cold water (5 mL) was added to the reaction liquid for quenching, and this was extracted with ethyl acetate (30 mL). The resultant organic layer was washed with 20percent saline water (30 mL), dried with sodium sulfate and concentrated to give a crude product (2.54 g). This was purified through silica gel chromatography to give 1.04 g (yield 43.4percent, purity 98.5percent) 2-(4-benzyloxybutyl)pyridine (invention product 1).
