Reaction Steps

This material was prepared from 7-chlorothieno[3,2-b]pyridine-2-carboxylic acid (1.05 g, 4.94 mmole), SOCl2 (10 ml), tert-butyl methyl[(3R)-pyrrolidin-3-yl]carbamate 34b (0.989 g, 4.94 mmole) and Et3N (0.689 ml, 4.94 mmole) in a manner as previously described for example 9d to give a brown oil (0.723 g, 0.30%). 1H NMR (300 MHz, CDCl3) δ8.62 (1H, d, J=5.1 Hz), 7.85 (1H, s), 7.35 (1H, d, J=5.1 Hz), 4.82 (1H, m), 3.93 (3H, m), 3.63 (1H, m), 2.82 (3H, s), 2.12 (2H, m), 1.47 (9H, s); ESIMS (MH+): 396.05.
