Procedure

To a chloroform solution 2 ml of 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-(5,6,7,8-tetrahydroimidazo[1,2-a]pyrazin-7-yl)-2-benzylthiopyrimidine (prepared in the above (4)) 104 mg is dropped a solution of m-chloroperbenzoic acid 43 mg in chloroform 3 ml over a period of 20 minutes on an ice bath, and the mixture is stirred for 1 hour. The reaction mixture is diluted with an aqueous saturated sodium hydrogen carbonate and extracted with ethyl acetate. The organic layer is washed, dried and concentrated in vacuo to give 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-(5,6,7,8-tetrahydroimidazo[1,2-a]pyrazin-7-yl)-2-benzylsulfinylpyrimidine as a slightly yellow caramel.
