Reaction Steps

To a solution of methylhydroxylamine HCl salt (17 mg, 0.2 mmol) in anhydrous MeOH (2 mL) was added NaOMe (25% in MeOH (Wt. %), 0.10 mL, 0.2 mmol), followed by (E)-N-(6-(3-cyanophenyl)-2-(pyridine-3-yl)chroman-4-ylidene)cyanamide (70 mg, 0.2 mmol). After stirring for 10 mins, the solvent was removed in vacuo. The resulting residue was redissolved in DCM (5 mL). The mixture was filtered, and the solvent was removed to give the residue, which was purified by preparative TLC and preparartive HPLC to give 3-(3′-amino-2′-methyl-2-(pyridine-3-yl)-2′H-spiro[chroman-4,5′-[1,2,4]oxadiazole]-6-yl)benzonitrile (2.5 mg, 3%). 1H-NMR (MeOD): 2.40-2.47 (t, 1H), 2.92-3.16 (m, 1H), 3.46 (s, 3H), 5.61-5.69 (m, 1H), 7.21 (m, 1H), 7.64-7.67 (m, 1H), 7.75 (d, 1H), 7.81-7.88 (m, 2H), 7.96-8.00 (t, 1H), 8.04-8.10 (t, 2H), 8.40 (m, 1H), 8.43 (m, 1H), 8.75 (s, 1H).
