Methylamine → Ammonia

Participants

Reaction Steps

To the suspension of 1-{4-[2-(2,3-dihydro-benzo[1,4]dioxin-6-ylamino)-pyridin-4-yl]-phenyl}-ethanone (Example 7, 0.19 g, 0.55 mmol) in 2 mL of MeOH was added a solution of methylamine in MeOH (Aldrich Chemical Company) (2N, 0.55 mL, 1.1 mmol). The reaction was stirred at room temperature under nitrogen overnight. NaBH4 (Aldrich Chemical Company) (25 mg, 0.66 mmol) was then added to the reaction and it was stirred for another 5 hrs. The solvent was dichloromethane:2N NH3 in MeOH) to give the title compound as an off-white foam. MS (ESI, pos. ion) m/z: 349 (M+1). Mp: 55.9-61.5° C.
