Reaction Steps

A mixture of the product of Step 3 (11.59 g, 24.2 mmol), THF (125 mL), MeOH (60 mL), H2O (30 mL) and 10 N NaOH (10 mL) was stirred at r.t. overnight. The mixture was then acidified with 2N HCl and the product was extracted in EtOAc, the extracts were dried over Na2SO4, and the product was purified by flash chromatography on silica with EtOAc:toluene:AcOH 5:95: 1. It was then swished in ether:hexane 1:2 to yield 10.29 g, 94%, of the title product. 1H NMR (CD3COCD3) 1.50 (3H, d), 2.38 (3H, s), 4.05 (1H, q), 5.44 (2H, s), 6.95 (2H, d), 7.16 (1H, dd), 9.28 (1H, d), 7.47 (2H, d), 7.80 (1H d).
