Reaction Steps
This compound was prepared from tert-butyl 2-{(2,5-difluorobenzyl)[(4-{4-[((2R)-2-hydroxy-2-{4-hydroxy-3-[(methylsulfonyl)amino]phenyl}ethyl)amino]-1-piperidinyl}phenyl)sulfonyl]amino}acetate in substantially the same manner, as described in Example 53, with one change; the mixture was stirred at room temperature for 20 hours. The volatiles were removed and the product was purified by reverse phase chromatography to give a white solid (1.44 9, 42% yield): mp 80-82° C.; MS m/e 669 (M+H)+; 1H NMR (DMSO-d6 400 MHz) 81.62 (m, 2H), 2.11 (m, 2H), 2.85 (m, 2H), 2.94 (s, 3H), 2.96 (m, 1H), 3.11 (m, 1H), 3.34 (m, 1H), 3.88 (s, 2H), 3.99 (m, 2H), 4.37 (s, 2H), 4.79 (m, 1H), 6.01 (br, 1H), 6.90 (d, 1H), 7.05 (m, 3H), 7.18 (m, 3H), 7.21 (s, 1H), 7.59 (d, 2H), 8.58 (brs, 1H), 8.66 (brs, 1H), 8.74 (brs, 1H), 10.01 (brs, 1H); Analysis for C29H34F2N4O8S2×2.0 CF3COOH×0.73 H2O Calc'd: C, 43.52; H, 4.11 ; N, 6.15 Found: C, 42.95; H, 3.93; N, 6.08.
