Reaction Steps

Following a literature procedure (Chakraborti, A. K.; Rudrawar, S.; Kondaskar, A. Eur. J. Org. Chem. 2004, 3597-3600) LiBr (0.001 g, 0.010 mmol) and m-anisidine (0.011 mL, 0.102 mmol) were added to ethyl 8-Methyl-5-(oxiran-2-ylmethyl)-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (0.032 g, 0.102 mmol) and stirred vigorously at ambient temperature overnight. Upon completion the reaction was partitioned between EtOAc/H2O, and the organic layer was concentrated to an orange oil.
