Procedure

A mixture of N7-methylquinoline-7,8-diamine (1.0 g, 5.8 mmol) and 2-hydroxy acetic acid (2.2 g, 29 mmol) was stirred at 115° C. for 2 h. Then saturated sodium bicarbonate solution was added. The mixture was extracted with EtOAc. The organic layer was concentrated to give a residue which was purified by silica gel column chromatography (eluting with DCM/MeOH v/v 30:1) to give (3-methyl-3H-imidazo-[4,5-h]quinolin-2-yl)methanol as a yellow solid (1.0 g, yield 83%). ESI MS: m/z 214 [M+H]+.
