실험 절차

Octahydro-indole-1,2-dicarboxylic acid 1-tert-butyl ester 89 (Bachem, 1.6 g, 1.0 eq) in DMF (20 mL) was treated with PyBOP (3.41 g, 1.1 eq) and NMM (1.97 mL, 3.0 eq). To this was added 3-amino-2-hydroxy-hexanoic acid cyclopropylamide 90 (1.22 g, 1.1 eq, prepared according to the procedure of U. Schoellkogf et al., Justus Liebigs Ann. Chem. GE, pp. 183-202 (1976) and J. Semple et al., Org. Letters, 2, pp. 2769-2772 (2000) and NMM (1.97 mL, 3.0 eq) in DMF (3 mL) and the mixture stirred at rt overnight. The mixture was evaporated in vacuo, diluted with ethyl acetate, the organic phase washed with 0.5N HCl, sodium bicarbonate and brine, then dried over sodium sulfate, filtered and concentrated in vacuo to give 2-[1-cyclopropylcarbamoyl-hydroxy-methyl)-butylcarbamoyl]-octahydro-indole-1-carboxylic acid tert-butyl ester 91 which was used without further purification. 1H NMR (CDCl3) δ 6.92 (bs, 1H), 6.80 (bs, 1H), 3.80-4.20 (m, 3H), 2.75 (m, 1H), 2.25 (m, 1H), 2.10 (m, 1H), 1.90-2.00 (m, 2H), 1.5-1.75 (m, 7H), 1.45 (s, 9H), 1.10-1.40 (m, 5H), 0.90 (m, 3H), 0.75 (m, 2H), 0.50 (m, 2H) ppm.
