63% | With carbon tetrabromide; triphenylphosphine In dichloromethane at -20 - 20℃; for 19.5 h; | To a solution of the compound of Example 2(c) (0.67 g, 3.1 mmol) in dichloromethane (35 mL) at -20 0C was added CBr4 (2.06 g, 6.17 mmol) followed by dropwise addition of a solution of PPh3 (1.70 g, 6.48 mmol) in dichloromethane (25 mL). The reaction mixture was held at -15 0C for18 h then stirred at room temperature for 1.5 h. The solvent was removed under reduced pressure and the residue purified by flash chromatography (silica gel, EtOAc/hexanes) gave 0.55 g (63percent) of product that was used in the next step. |

37% | With triphenylphosphine In dichloromethane | Step B: 2-Bromomethylmorpholine-4-carboxylic acid tert-butyl ester To a cooled (0° C.) solution of 2-hydroxymethylmorpholine-4-carboxylic acid tert-butyl ester (1.04 g, 4.79 mmol, see Step 1) in dichloromethane (20 mL) was added CBr4 (1.98 g, 5.98 mmol). After stirring the mixture for 10 minutes, triphenylphosphine (2.20 g, 8.38 mmol) was added portion-wise. The reaction mixture was stirred at 0° C. for 6 hours and then allowed to warm to room temperature and stirred for 60 hours. The mixture was concentrated under reduced pressure and then diluted with ether. The crude mixture was filtered and the filtrate was concentrated to afford the crude product, which was chromatographed on Biotage eluding with dichloromethane. The desired fractions were combined and concentrated to yield 0.50 g of product (37percent yield). |
