Procedure

To a solution of {3-[1-(5-Benzyl-3-methyl-4-oxo-4,5-dihydro-isothiazolo[5,4-d]pyrimidin-6-yl)-2-methyl-propylamino]-propyl}-carbamic acid tert-butyl ester obtained from method 31 alternative procedure above in chloroform (300 ml), diisopropylethylamine (6 g, 46.5 mmol) was added and the reaction mixture was heated to 60° C. To the hot solution a solution of the p-toluoyl chloride (3.78 g, 24.4 mmol) in chloroform (150 ml) was added dropwise and the resulting solution was refluxed overnight. The TLC showed the disappearance of most of the SM. The reaction mixture was washed with water (2×100 ml), satd, NaHCO3 (200 ml) brine (100 ml) and dried (Na2SO4). Concentration of the organic layer provided the crude product which was purified by column (silica gel) chromatography using 10-30% EtOAc in hexanes as eluent. Yield=6.14 g (62%) of {3-[[1-(5-benzyl-3-methyl-4-oxo-4,5-dihydro-isothiazolo[5,4-d]pyrimidin-6-yl)-2-methyl-propyl]-(4-methyl-benzoyl)-amino]-propyl}-carbamic acid tert-butyl ester. White foam, mp. 70-71° C. m/z 604 (MH+), 1H NMR (DMSO-d6, 300 MHz, 95° C.) δ: 0.48 (d, 3H), 0.90 (d, 3H), 1.26 m, 1H), 1.28 (s, 9H), 2.33 (s, 3H), 2.47 (d, 2H), 2.72-2.64 (m, 1H), 2.72 (s, 3H), 3.24 (t, 2H), 5.08 (d, 1H), 5.60 (d, 1H), 5.90 (d, 1H), 7.20-7.40 (m, 9H).
