Reaction Steps
(2R,3S)-β-phenyl-isoserine methyl ester (4.35g, 22 mM) is dissolved in 100 ML dry THF and the flask cooled to 0° C. To the solution is added t-butyl isocyanate (2.8 mL, 25 mM). TLC after 15 minutes shows some starting material left so another 0.5 mL of the isocyanate is added. TLC after 1 hour shows no starting material so the solvent is concentrated in vacuo.
