実験手順
The product of STEP 8 (67.5 mg, 0.17 mmol) was dissolved in 5 ml methanol and 5 ml 1N sodium hydroxide solution. The reaction was stirred at room temperature for 16 h, and acidified with trifluoroacetic acid (1.0 ml). Solvents were evaporated and residue was purified on HPLC using acetonitrile gradient 10-50% in 30 min to yield 31.5 mg. FAB-MS: (MH+)=373. H NMR(CDCl3) δ1.03 (s, 6H), 2.21 (p, 2H), 2.22 (s, 2H), 2.61 (s, 2H), 3.60 (q, 2H), 3.84 (s, 2H), 4.13 (t, 2H), 6.65-6.82 (m, 4H), 6.96 (d, 1H), 7.68-7.80 (m, 2H); Anal Calcd. for C21H28N2O4 plus 1.5 CF3COOH: C, 52.17; H, 5.56; N, 5.07. Found: C, 52.44; H, 5.62; N, 4.88.
