Potassium Carbonate → tert-butyl 2-[(2,3-dihydro-1H-inden-2-yl)amino]acetate

Participants

Reaction Steps

To a suspension of 2-aminoindane hydrochloride (5.0g, 29.5 mmol) and powdered K2CO3 (8.3 g, 60.0 mmol) in absolute EtOH (30 mL) was added tert-butyl bromoacetate (4.4 mL, 29.5 mmol). After stirring for 10 min at rt the reaction was heated to 45° C. and stirred for 2 hr. The reaction was cooled to rt, diluted with EtOAc, filtered and concentrated. Chromatography of the residue on silica gel (elution with 20% EtOAc:hexane) provided 4.7g of compound 721 as a white crystalline solid. ##STR100##
