Procedure
The title compound of Example 157 (168 mg, 0.0004 mol) in dry THF (2 mL) with tert-butoxycarbonylglycine (70 mg, 0.0004 mol) was treated with dicyclohexylcarbodiimide (82.4 mg, 0.0004 mol) in dry THF (2 mL). The solution was stirred 16h at 23°; filtered and stripped to dryness. The residue was taken up in methylene chloride (5 mL) and applied to a Chromatotron™ Rotor Plate (1000 u thickness); plate eluted with methylene chloride-methanol gradient (0% to 3% MeOH). This afforded 122 mg (52%) of the title compound as a light red solid. LC MS (m/e)=583(MH+). Rt=2.12 min.
