Procedure

A mixture of N-cyclopropyl-2-(2,5-dichloropyrimidin-4-yl)-1-(ethoxymethyl)-1H-indole-4-carboxamide (10 g, 25 mmol), (1S,2R)-2-aminocyclopentanol hydrochloride (4.1 g, 30 mmol) and DIPEA (5 mL, 30 mmol) in DMSO (70 mL) is stirred at 100° C. for 3 h, then poured into water and extracted with EA. The combined extracts are washed with aqueous saturated sodium chloride, dried over Na2SO4 and concentrated in vacuo. The residue is purified by chromatography on silica gel to give 2-{5-chloro-2-[(1R,2S)-2-hydroxycyclopentylamino]pyrimidin-4-yl}-N-cyclopropyl-1-(ethoxymethyl)-1H-indole-4-carboxamide (7 g, 60.3%). MS (m/z): 470 (35Cl) and 472 (37Cl) (M+H)+
