Procedure
A solution of 1-(4-triflouromethylphenylsulphonyl )-4-[1-(6-chloro-pyrimidin-4-yl)piperazin-4-ylcarbonyl]piperazine (26.0 g) in 33% methylamine in ethanol (400 ml) was heated at 110° C. in a Carius tube for 8 hours. The mixture was evaporated to dryness and the residue recrystallised from methanol to give, as a solid 1-(4-triflouromethylphenylsulphonyl)-4-[1-(6-metliylamino-pyrimidin-4-yl)piperazin-4-ylcarbonyl]piperazine (13.67 g), mp 230-231° C. Found C, 49.10; H, 4.90 and N, 19.00%. C21H26F3N7O3S requires C, 49.12; H, 5.10 and N, 19.09% NMR (CDCl3): 2.85 (d, 3H), 3.10 (m, 4H), 3.30 (m, 4H), 3.40 (m, 4H), 3.60 (m, 4H), 4.75 (m, 1H), 5.40 (s, 1H), 7.80 (d, 2H), 7.90 (d, 2H) and 8.15 (s, 1H); m/z 154 (M+1).
