実験手順
Following a procedure similar to that described in Example 27, but using 460 mg of N-[2-(4-methoxycarbonylmethylphenoxy)-1(S)-methylethyl]-2(R)-t-butyldimethylsilyloxy-2-phenylethanamine (prepared as described in Preparation 31), 15 ml of tetrahydrofuran and 780 mg of tetrabutylammonium fluoride, 0.23 g of the title compound was obtained as crystals, melting at 89°-90° C.
