YieldReaction ConditionsOperation in experiment
98% at 20 - 35℃; for 2 h; Methanesulfonic acid (8.46 g, 88 mmol) was added to a suspension of nelfinavir base (50 g, 88 mmol) in acetone (400 ml) at 25-35°C, and stirred to obtain a clear solution. Stirred the reaction mixture for ~2 h at 20-25°C, and the precipitated product was collected by filtration and washed with acetone (100 ml). This was dried at 70-75°C under reduced pressure till LOD was -8percent w/w to yield 57.5 g (98percent) of the title compound having the purity > 99.5percent (HPLC) and the product is crystalline by XRD.

Stage #1: at 25 - 30℃; for 0.166667 h;
Stage #2: at 25 - 30℃; for 0.25 h; Carbon
Stage #3: at 40 - 55℃; for 1 h;
To a suspension of nelfinavir base (10 g, 17.6 m. mol) in methanol (50 ml) added methanesulfonic acid (1.69 g, 1.76 m mol) was added and stirred for 10 min at 25- 30°C. The resulting clear solution was treated with carbon (1 g) for 15 min at 25- 300C. The carbon was removed by filtration through hyflo and washed with 10 ml of methanol. The combined filtrate was concentrated at 40-450C under reduced pressure (150-20 mm Hg) till no more solvent distills out, leaving a foamy residue. This was further kept at 50-550C under reduced pressure (10-20 mm Hg) for 1 h, cooled to 25-3O0C, added 50 ml of cyclohexane and stirred for 15 min at 25-3O0C. The resulting free flowing product was filtered and washed with cyclohexane (10 ml). The product was dried at 70-75°C for 4 h under reduce pressure (10-20 mm Hg) to obtain 1 1.0 g (92percent) of the title compound.Total solvents are < 0.1percent w/w (By GC) and the product was amorphous by XRD.
77% at 0 - 45℃; for 5.83333 h; Nelfinavir base (20 g) is suspended in ethanol (30 ml), and methanesulfonic acid (3.4 g) is added at temperature of 28°C to 45°C over 20 min. The reaction mixture is maintained at 40°C to 45°C for lhr to get clear solution. The obtained clear solution is cooled to 28°C to 30°C and methyl isobutyl ketone (58 ml) is added over 30 min, mixed at temperature of 28°C to 30°C for 2 hrs. The reaction mass is cooled and maintained at 0°C to 5°C for 2 hr. The precipitated solid is filtered, washed with chilled methyl isobutyl ketone (10 ml) and dried at 90°C to 100°C under vacuum till becomes constant weight.Out put: 18 g (77 percent of the theoretical)
76% for 2 h; Procedure for Precipitation of Nelfinavir Free Base to Obtain Nelfinavir Mesylate; Alternatively, nelfinavir free base can be converted to nelfinavir mesylate using the following novel precipitation procedure. Nelfinavir free base is slurried or dissolved in a suitable solvent (such as THF, methanol, or ethanol). THF is the preferred solvent. A molar equivalent amount of methanesulfonic acid is added, and the mixture is stirred until all solids dissolve. The solution is added to several volumes of an antisolvent (such as methyl t-butyl ether, diethyl ether, hexanes, or heptanes) that is rapidly stirring. Diethyl ether is the preferred antisolvent. After stirring, the mixture is filtered and washed with antisolvent. The solid is dried in a vacuum oven to yield nelfinavir mesylate. Specifically, this conversion was performed as described below. Nelfinavir free base (10.2 kg, 18.0 mol) and 24 L of tetrahydrofuran were added to a 100L reactor. Methanesulfonic acid (1.8 kg, 18.48 mol) also was added to the reactor. The reactor was stirred until all solids dissolved, and then the solution was filtered into a 100 gallon polypropylene tank containing 306 L methyl t-butyl ether or diethyl ether that was rapidly stirring. After stirring for 2 hours, the 100 gallon tank contents were filtered, washed with 17 L of methyl t-butyl ether or diethyl ether, and pulled as dry as possible. The solid was transferred to a rotocone drier and dried in a vacuum oven at 60-65°C (at least 26 in. Hg or higher vacuum) for 12-72 hours or until the methyl t-butyl ether or diethyl ether content of the dried solid was below 1percent. If necessary, the drier contents could be milled in a Fitzmill grinder to accelerate drying. Typical yields of nelfinavir mesylate range from 9 to 11 kg. (76percent - 92percent theory).
