Participants

Reaction Steps

Freshly distilled benzyl glyoxylate (312 mg, 1.9 mmol) and freshly distilled tetrahydrofuran (15 ml) were stirred with 4A molecular sieves for one hour and then cooled in ice. To this solution was added the solid product from Example 5 (437 mg, 1.19 mmol) followed by the dropwise addition of triethylamine (240 mg, 2.37 mmol). The ice bath was removed and the reaction was stirred for 1.5 hours. The solution was filtered and the filtrate was evaporated to dryness. The residue was dissolved in chloroform and chromatographed on a silica gel column with a chloroform-ethyl acetate gradient as eluant to give the title product, 525 mg (83%).
