Reaction Steps

A solution of 0.091 g (0.65 mmol) of 3-methoxy-benzenethiol in 4 drops of piperidine is stirred at room temperature for 5 minutes. A quantity of 0.200 g (0.65 mmol) of 2-tert-butoxycarbonylamino-3-(3-methoxyphenyl)acrylic acid, methyl ester of Example 30 is added and the solution is heated at 60° C. for 24 hours. Ethyl acetate (120 mL) is added and the solution is washed with 3×80 mL of 1N sodium hydroxide and brine (80 mL). After drying (magnesium sulfate), the solution is evaporated and the residue is purified by silica gel chromatography, eluting with 20% ethyl acetate-hexane to give the product as an inseparable mixture of diastereomers; wt 0.26 g (89%);
