A suspension of 3-methoxycarbonylmethyl-2-oxo-1,2,3,4-tetrahydro-quinoline-7-carboxylic acid tert-butyl ester (3.5 g, 13.2 mmol) in dioxane (40 mL) was treated with 10 mL of 4N hydrochloric acid in dioxane and heated to 40-50° C. Evaporation of the volatiles in vacuo gave the title compound (3.35 g, 97%). NMR (dmso-d6, 200 MHz) : δ2.7-3.4 (m, 5H, CH2CHCH2), 3.6 (s, 3H, CH3), 7.2-7.5 (m, 3H, ArH), 10.3 (s, 1 H, NH).
