The reaction was quenched by the addition of water (1 mL) and aqueous 2N NaOH (1 mL). The resulting precipitates were removed by filtration and the filtrate was concentrated to afford (4-(isopropylamino)-6-(methoxy(methyl)amino)pyridine-3-yl)methanol (2.9 g, >100% yield), which was used without further purification. 1HNMR (400 MHz, DMSO-d6): δ 7.62 (s, 1 H), 6.16 (s, 1 H), 5.44 (d, J=7.2 Hz, 1 H), 5.02 (bs, 1 H), 4.33 (s, 2 H), 3.69-3.61 (m, 4 H), 3.06 (s, 3 H), 1.18 (d, J=6.4 Hz, 6 H).
