Reaction Steps

To a solution of N-methyl-4-nitroaniline (5 g, 32.9 mmol) in DMF (75 ml) was slowly added NaH (60% in mineral oil, 4.21 g, 105 mmol) at RT (Warning: important gaz evolution occurred!). The suspension was vigorously stirred at RT for 15 min then cooled to 0° C. (ice bath). 4-(Chloromethyl)pyridine hydrochloride (8.09 g, 49.3 mmol) was added carefully then the slurry was allowed to warm to RT and further stirred for 45 min. The reaction mixture was poured into water and extracted with Et2O (3×). The combined organic phases were dried over Na2SO4, filtered and evaporated to dryness to yield the crude title compound (10.13 g) as an orange solid, which was used in the next step without further purification. HPLC: AtRet=1.01 min; LC-MS: m/z 244.5 [M+H]+; 1H NMR (400 MHz, DMSO-d6): 3.23 (s, 3H), 4.82 (s, 2H), 6.77-6.83 (m, 2H), 7.17-7.22 (m, 2H), 8.02-8.08 (m, 2H), 8.49-8.54 (m, 2H).
