Reaction Steps
To a solution of (7-benzenesulfonyl-4-oxo-chroman-2-ylmethyl)-methyl-carbamic acid tert-butyl ester (155 mg, 0.359 mmol) in MeOH (50 mL) were added Pd(OH)2 (10 mg) and HCl (concentrated, 5 drops) the mixture was shaken into a Parr apparatus under H2 atmosphere (50 PSI) for 3 hours. The reaction was filtered through a celite pad and the filtrate was neutralized with Na2CO3. The mixture was filtered and the filtrate was concentrated in vacuo. The residue purified via flash chromatography (DCM/MeOH, 99/1) to give (7-benzenesulfonyl-chroman-2-ylmethyl)-methyl-carbamic acid tert-butyl ester (147 mg, 98% yield) as a clear glass.
