実験手順
The guanidine (b) was dissolved in HCl (5 mL, 6 M) at 0° C. and then stirred for 2 h. After the starting material was consumed, NaOH (25%) was added until a precipitate formed. This mixture was stirred for 30 min. The reaction was then poured into NaOH (0.5 M), extracted with CH2Cl2, dried and concentrated. Flash chromatography afforded (c) (0.95 g, 50%). NMR (500 MHz, DMSO-d6) δ 8.58 (s, br, 1H), 7.34-6.74 (m, 5H), 6.68 (s, 2H), 6.62 (br, 2H), 3.82 (s, 6H), 3.73 (s, 3H). MS: 157.6 (M−H)−; 160.0 (M+H)+.
