Procedure

A mixture of (R)-3-(2-chlorobenzamido)-N-methyl-N-(piperidin-4-yl)-2,3-dihydro-1H-indene-5-carboxamide (stage 2H-214) (200 mg, 0.486 mmol, 1.0 eq), 4-chloro-pyrimidin-2-ylamine (94 mg, 0.728 mmol, 1.5 eq) and DIPEA (0.125 ml, 0.728 mmol, 1.5 eq) in dioxane (10 ml) was refluxed for 16 h. When the reaction was complete according to TLC monitoring, concentration under reduced pressure was carried out, and the reside was taken up in dichloromethane (50 ml) and washed with water (30 ml) and saturated sodium chloride solution (30 ml). The organic phase was dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by column chromatography (silica gel, 6% methanol in dichloromethane). Yield: 45% (110 mg, 0.267 mmol) Analytical Data—Single Substances Method 1: Equipment and methods for HPLC-MS analysis: HPLC: Waters Alliance 2795 with PDA Waters 2998; MS: Micromass Quattro Micro™ API; column: Waters Atlantis® T3, 3 μm, 100 Å, 2.1×30 mm; column temperature: 40° C., eluent A: purified water+0.1% formic acid; eluent B: acetonitrile (gradient grade)+0.1% formic acid; gradient: 0% B to 100% B in 8.8 min, 100% B for 0.4 min, 100% B to 0% B in 0.01 min, 0% B for 0.8 min; flow: 1.0 ml/min; ionization: ES+, 25 V; batch: 100 μl/min 70% methanol+0.2% formic acid; UV: 200-400 nm.
