6-Methyl-7-propyl-5,7,13-triazatetracyclo[9.3.1.02,10.04,8]pentadeca-2(10),3,5,8-tetraene-13-carboxylic acid tert-butyl ester (90 mg, 0.253 mmol) was dissolved in 3N HCl ethyl acetate (5 mL) and warmed to 100° C. for ½ hour. The mixture was cooled, concentrated, slurried in ethyl acetate, and filtered to provide a white solid (25 mg, 34%). 1H NMR (400 MHz, DMSO-d6) δ 9.56 (s, NH), 7.91 (s, 1H), 7.83 (br m, NH), 7.74 (s, 1H), 4.38 (m, 2H), 3.48 (m, 2H), 3.32 (m, 2H), 3.10 (m, 2H), 2.87 (s, 3H), 2.28 (m, 1H), 2.15 (d, J=11.0 Hz, 1H) 1.85 (m, 2H), 0.97 (m, 3H). M.p. 147–150° C.
