1-(chloromethyl)-2-propan-2-yloxybenzene

Conditions: temp:8.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Solid magnesium turnings (4.6 g, 48 equiv.) under nitrogen atmosphere at room temperature were stirred vigorously with a magnetic stirring bar overnight. The magnesium was then covered with dry tetrahydrofuran. A cold bath was then applied followed by dropwise addition of 1-chloromethyl-2-isopropoxy-benzene (3.0 g, 4 equiv. prepared as described above) in tetrahydrofuran (40 mL). During slow addition of the electrophile no exotherm was observed so on completion of addition 3 crystals of Iodine were added to promote initiation of the reaction. After this addition the reaction temperature was allowed to spike to 50° C. then cooled rapidly to 8° C. before being left to warm to room temperature for one hour. The resulting black suspension was cooled down to −10° C. and a solution of (4-Benzyl-morpholin-2-yl)-phenyl-methanone (1.2 g, 1 equiv.) in tetrahydrofuran (10 mL) was then added dropwise. The reaction mixture was left to warm to room temperature over thirty minutes and then quenched by addition of aqueous saturated solution of NaHCO3 (50 mL) prior to filtration through Celite. The aqueous solution was extracted with diethyl ether, the organic phase dried with MgSO4, evaporated in vacuo to give 3 g of a yellow amorphous solid. The compound was taken without further purification in the next step. LCMS (6 minutes method) [M+H]+=432 @ Rt 3.25 min. major peak. During slow addition of the electrophile no exotherm were added initiation of the reaction After this addition the reaction temperature to spike to 50° C. before being left to warm to room temperature for one hour The resulting black suspension was cooled down to −10° C.
