Ethyl (S)-2-(trifluoromethylsulfonyloxy)propionate → n-({4-[(3-Chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)-n-(2-pyrrolidin-1-ylethyl)-d-alanine

Participants

Reaction Steps

N-(3-Chloro-2-fluorophenyl)-7-methoxy-6-{[(2-pyrrolidin-1-ylethyl)amino]methyl}quinazolin-4-amine (prepared as described in Example 47) was coupled with ethyl O-trifluoromethanesulfonyl-L-lactate and hydrolysed using analogous methods to those described for the equivalent steps in Example 46 to give N-({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)-N-(2-pyrrolidin-1-ylethyl)-D-alanine; 1H NMR Spectrum: (DMSO-d6) 1.27 (d, 3H); 1.83 (m, 4H); 2.86 (m, 8H); 3.44 (q, 1H); 3.84 (d, 1H); 3.94 (d, 1H); 4.01 (s, 3H); 7.25 (s, 1H); 7.33 (t, 1H); 7.53 (m, 1H); 7.63 (m, 1H); 8.42 (s, 1H); 8.48 (s, 1H); 9.78 (brs, 1H); Mass Spectrum: (M+H)+ 502.
