Reaction Steps

0.59 ml (3.38 mmol) of N,N′-diisopropylethylamine and 248 mg (1.58 mmol) of 3-chlorobenzoic acid were added to a solution of the compound from Example 62A (500 mg, 1.06 mmol) in N,N′-dimethylformamide (18 ml). After addition of 522 mg (1.37 mmol) of HATU, the mixture was stirred at RT overnight. The reaction mixture was purified directly by preparative HPLC(RP18 column; acetonitrile/water gradient). Yield: 414 mg (67% of theory)
