Ammonium Hydroxide → 2-Amino-6-chloro-N-methoxy-N-methyl-nicotinamide

Participants

Reaction Steps

2,6-Dichloro-N-methoxy-N-methyl-nicotinamide (202.4 mg, 0.8610 mmol, Example 1) and concentrated ammonium hydroxide (1.8 mL, 29.4%, Fisher) in tetrahydrofuran (2.5 mL) were heated to 155° C. in the microwave for 2 hr. The reaction mixture was concentrated and the residue was purified on silica gel with hexanes/ethyl acetate to give 2-Amino-6-chloro-N-methoxy-N-methyl-nicotinamide (14.3 mg, 8% yield). HRMS, observed: 215.0463, Calcd for M+: 215.0462.
