Yield: 97%
Reaction Conditions:
with hydrogen;10% palladium on activated carbon in methanol at 40 - 50; under 760.051 Torr; for 1.5 h;
Steps:
8.b EXAMPLE 8; 3-Methoxythieno[2,3-b]pyridine-2-carboxylic acid [8-(4-chlorobenzyl)-8-azabicyclo[3.2.1]oct-3β-yl]amide hydrochloride; b) ter-Butyl-N-(8-azabicyclo[3.2.1]oct-3 β-yl)carbamate
1.6 g of ter-butyl-N-[8-(phenylmethyl)-8-azabicyclo[3.2.1]oct-3β-yl]carbamate (5.05 mmol, 1 eq.) dissolved in 80 ml of methanol is hydrogenated at atmospheric pressure at 45-50° C. in the presence of 0.1 g of 10% palladium-coated charcoal for 90 min. The catalyst is filtered, rinsed with methanol and vacuum evaporated. 1.1 g (97%) of the secondary amine product is obtained. FP=123° C. NMR (1H, CDCl3): 1.30 (m; 2H), 1.41 (s; 9H) , 1.74 (m; 4H), 1.88 (m; 2H), 3.52 (m; 2H, H1 and H5), 3.78 (m; H1, H3), 4.34 (m; 1H; NH-carbamate)
