Procedure

2-[(5-Bromo-4-pyrimidinyl)amino]-1-butanol (3.3 g) was dissolved in xylene (27 mL), then thionyl chloride (4.9 mL) was added thereto, and the mixture was heated under stirring at 100° C. for 1 day. The precipitated crystals were collected by filtration and suspended in a 1M aqueous sodium carbonate solution. This mixture was extracted with dichloromethane to give the crude title compound (3.0 g) as an orange oil. This title compound was used in the next reaction without purification.
