Reaction Steps
Heat a solution of methyl 4-aminobutanoate hydrochloride (11 g, 71.9 mmol), benzylbromide (25.2 g, 147.3 mmol) and K2CO3 (21.8 g, 158.2 mmol) in MeCN (200 mL) at 40° C. overnight. Concentrate the mixture to dryness, pour the residue into water, extract with EtOAc (3×), wash the combined organics with brine, dry over Na2SO4, concentrate and purify via silica gel chromatography to give the title compound (19.5 g, 91%). 1H NMR (400 MHz, DMSO-d6): δ 7.33-7.18 (m, 10H), 3.57 (s, 3H), 3.52 (s, 4H), 2.43-2.28 (m, 4H), 1.83-1.76 (m, 2H).
