79% With benzotriazol-1-yloxyl-tris-(pyrrolidino)-phosphonium hexafluorophosphate; N-ethyl-N,N-diisopropylamine In ISOPROPYLAMIDE for 14h; 1 Example 1; Preparation of Compound IIa4-1 from (-) menthyl chloride. 1.39 grams of Mg metal (57 mmol) was placed in a 100 mL flask and 4 mL of dry THF was added to cover the Mg metal. A crystal of iodine was added to the metal-THF mixture and stirred for several minutes followed by the addition of about 1/3 portion of 10 grams (57 mmol) of (-) menthyl chloride (Aldrich). The mixture was heated to induce Grignard formation and the remaining menthyl chloride (2/3 portion) was added in 50 mL dry THF and stirred until the reaction was complete. The Grignard solution was then canulated under nitrogen into a vessel containing excess dry ice. This dry ice quenched mixture was swirled and poured into 300 mL ice containing 2 mL concentrated HC1. Diethyl ether was added and the mixture separated. The separated organic layers were combined and washed with water then extracted with an aqueous NAOH solution. The aqueous solution (and oil) was acidified with HCl until a solid formed, diethyl ether was added, and the acid was extracted into the organic phase, washed with brine, dried over sodium sulfate, and concentrated to give 4. 18 grams (40%) as white needles. The acid (0.57 grams, 3.1 mmol) was dissolved in 1.5 mL dimethylacetamide (DMA). The PyBOP (2.1 grams, 4.0 mmol), p-anisidine (0.58 grams, 4.7 mmol, Aldrich) and DIPEA (2.7 mL, 15.5 mmol) were added. Another 0.25 grams p-anisidine was added after 2 hours and again after 5 hours. The reaction was diluted with ethyl acetate (EtOAc) after 7 hours, washed twice with 1 N HCl, twice with aqueous sodium bicarbonate, and then with brine. The separated organic layers were combined and dried over sodium sulfate and concentrated to a brown solid. This solid was put through a plug of silica gel with 30% EtOAc/hexanes to remove the color. The product began to crystallize upon concentration, so the crystallization was allowed to occur, the solvent was removed by pipette, and the white needles were washed with cold EtOAc and dried under vacuum to give 0.365 grams (1.26 mmol, 40% yield) of a first crop. Recrystallization of the mother liquor yielded an additional 0.346 grams (1.2 mmol, 39% yield) as white needles. LCMS showed the product to have a molecular weight of 289, corresponding to the desired molecular weight, and the NMR spectra showed it to have the desired structure.
