Reaction Steps

A solution of methyl (1S,2R,4R)-4-hydroxy-2-methoxycyclohexanecarboxylate (racemic) (1.14 g, 6.06 mmol) in dichloromethane (30 mL) was treated with methanesulfonyl chloride (0.938 mL, 12.1 mmol) dropwise at 0° C. The mixture was stirred at 0° C. for 2 h and partitioned between ethyl acetate and water. The organic phase was concentrated and purified on silica gel (eluting with 50% ethyl acetate in hexanes) to give the desired product (1.48 g, 93%). 1H NMR (400 MHz, CDCl3) δ 4.89 (1H, m), 3.70 (3H, s), 3.62 (1H, m), 3.36 (3H, s), 3.02 (3H, s), 2.78 (1H, m), 2.42 (1H, m), 2.01 (2H, m), 1.98 (1H, m), 1.80 (1H, m), 1.62 (1H, m) ppm.
