With dimethyl 1-(1-diazo-2-oxopropyl)phosphonate; potassium carbonate; In methanol; at 0 - 10℃; for 6h; | To a solution of dimethyl 1-diazo-2-oxopropyl phosphonate (see Ohira, S. Synth. Commun. 19, 561-564, (1989) ) (2.97 g, 15.5 mmol) in methanol (50 ml) at 0 C was added potassium carbonate (1.71g, 12.4 mmol) and slowly a solution OFN-BOC-2-AMINO-2-METHYL- propionaldehyde (1.45 g, 7.74 mmol) in methanol (5 ml). The reaction mixture was stirred at 0-10 C for additional 6 h, diluted with diethylether (-150 ml) and with saturated aqueous ammonium chloride solution (150 ml). The organic layer was washed with saturated aqueous ammonium chloride solution (100 ml), water (100 ml), and finally with brine, dried over sodium sulfate, and concentrated in vacuo. Purification by flash chromatography over silica gel using ethyl acetate/hexane (1/10) provided N-BOC-2-AMINO-2-METHYLBUT-3-YNE (1.38 g) as yellowish oil. |

74% | (67a) [1,1-Dimethyl-2-(3-fluoro-2-methylphenylamino)ethyl]carbamic acid t-butyl ester 5.8 g of sodium triacetoxyborohydride (27.0 mmol) was added to a solution of 3.5 g of (1,1-dimethyl-2-oxoethyl)carbamic acid t-butyl ester obtained in Reference Example 3 (18.7 mmol), 2.25 g of <strong>[443-86-7]3-fluoro-2-methylaniline</strong> (18.0 mmol) and 1.0 ml of acetic acid (18.0 mmol) in methylene chloride (190 ml) under ice-cooling, and the mixture was stirred at room temperature for 16 hours. A saturated sodium bicarbonate aqueous solution was added to the reaction mixture, followed by extraction with methylene chloride. Then, the organic layer was washed with brine and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate = 5/1) to obtain 3.97 g of the title compound (yield: 74percent). Colorless solid. 1H NMR spectrum (CDCl3, 400 MHz), delta: 7.04-6.98 (m, 1H), 6.43-6.36 (m, 2H), 4.57 (br s, 1H), 4.51 (br s, 1H), 3.29 (br s, 2H), 2.06 (br s, 3H), 1.43 (s, 9H), 1.39 (s, 6H). |
