Procedure

The further transformation of bromide x258 into the target product 240 is carried out in complete accordance with the transformation of bromide b191-1 into product ucb-108891-1 as described in examples 79.2 to 79.4. The yields are similar for intermediates 4-bromo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine x259, 1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine-4-carbaldehyde x260 and 4-propyl-{[1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridin-4-yl]methyl}pyrrolidin-2-one x261. As a result, 1.0 g (5.1 mmol) of 4-bromo-1H-pyrrolo[2,3-b]pyridine x258 affords 0.45 g of 4-propyl-1-(1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)pyrrolidin-2-one 240.
