Reaction Steps

Compound 12 (0.05 mg, 0.12 mmol) was added to 4 mL methylamine (40% sol. In water). The mixture was heated at 65° C. for 24 h. After concentration in vacuo, the residue was purified using prep. TLC (10% MeOH:DCM). 1HNMR (CD3OD) 62.90 (s, 3H), 3.78 (m, 1H), 3.91 (m, 1H), 4.13 (d, 1H), 4.34 (d, 1H), 4.64 (m, 1H), 6.06 (d, 1H), 8.11 (s, 1H), 8.38 (s, 1H), 9.05 (s, 1H).
