Yield	Reaction Conditions	Operation in experiment
96%	for 3 h; Reflux	In a 500 mL three-necked flask was added 50.0 g of Compound 3 powder and 250 mL of acetonitrile and 25 mL of acetic anhydride, stirred and refluxed for 3 h, cooled to room temperature and filtered with suction. The solid was washed with acetonitrile twice and the filter cake was dried to give 56.3 g of compound 4 with a yield of 96.0 percent.
95%	for 0.0111111 h; Microwave radiation	To a solution of cytidine (1.22 g, 5.00 mmol) in DMF(40 mL) is added acetic anhydride (0.94 mL, 10.00 mmol). The solution is treated with microwave radiation (Panasonic, 1000 Watts) at full power for 40 seconds. The solution is concentrated in vacuo and the residue is co-evaporated with methanol (2.x.20 mL) to give 4-N-acetyl-cytidine (1.43 g, 95.0percent) as a white powder. MS (FAB):m/z 286 (MH⁺).
87%	for 24 h;	Cytidine (100.Og, 0.41 mol) was dissolved in DMF (500 ml), acetic anhydride (42.5 ml, 45.9 g, 0.45 mol) was added and the whole was left for 24 h. Solvent was evaporated, the residue boiled with methanol (40 ml) and cooled. Crystals were filtered and dried to furnish Λ^-acetylcytidine (102 g, 87.0percent).
