Cyclopropylmethyl alcohol (0.921 ml, 11.4 mmol) was added to a stirring suspension of NaH (455 mg, 11.4 mmol) in DMF (20 ml) under an argon atmosphere. The resulting solution was allowed to stir at RT for 20 min. 6-chloro-7-fluoro-8-nitro-9H-β-carboline (500 mg, 1.9 mmol) was added to the stirring solution and the resulting mixture was allowed to stir at RT. Upon addition of H2O, a brown solid precipitated out which was filtered to give the desired 6-chloro-7-cyclopropylmethyoxy-8-nitro-9H-β-carboline (510 mg, 85%). 1H-NMR (300 MHz, DMSO-d6): δ 0.35 (m, 2H), 0.59 (m, 2H), 1.32 (m, 1H), 4.04 (d, 2H), 8.21 (d, 1H), 8.46 (d, 1H), 8.90 (s, 1H), 9.02 (s, 1H), 12.32 (b, 1H). Retention Time (LC, method: ammonium acetate standard): 2.63 min. MS (M+H+): 318.
