Reaction Steps
To a solution of (R)-4-(2-chloro-acetyl)-3-hydroxymethyl-piperazine-1-carboxylic acid tert-butyl ester (710 mg, 2.45 mmol) in THF (16 mL) at 0° C. was added potassium tert-butoxide (326 mg, 2.91 mmol). The resulting mixture was stirred for 75 min before the addition of AcOH (0.6 mL). The resulting mixture was partitioned between water and DCM and the aqueous layer extracted with further DCM. The combined organic fractions were dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified by column chromatography to give the title compound as a colourless oil (570 mg, 91%).
